The PC gaming platform is more prone to having more bugs in games (games not working as they should) over consoles for several reasons:
1. The platform is not uniform. This means someone has issues with drivers and so on, or some odd BIOS, then a game may not load. It also means that developers won't be able to test software against every possible configuration to see if it will work.
2. Consoles, when you game, are just doing gaming stuff, or basic stuff embedded in the operating system, such as notifying that friends are on. With the PC, you are running firewalls, anti-virus and other things to. These can cause memory conflicts. Factor in also how PC gaming is subject to piracy, and anti-piracy measures causing some games to not load. Multitasking = greater chances at failure, crashes and bugs.
3. PCs end up having various installs that update the internals of the operating system, in a manner than isn't uniform across all PCs.

End result is you are more prone to having buggy software on the PC, due to how a PC is made.

Its not bad at all imo, I don't see PC gaming as bugged to the extent that it ruins the experience. To this day, there are only two games I've played that had game crippling bugs and they were Thief 2: The Metal Age (the game itself is extraordinary though) where you simply couldn't finish one of the missions because you were never registered leaving the area after having completed your objectives. It took a 42MB patch and this was in the single line ISDN days so that was kind of a big deal.
The other game was Gothic 3, a good game at the core but it had way too many bugs for my taste.

My confidence in console game quality is not exactly undamaged either, huge blockbusters like the GTA series gets away with some really amazing (not in a good way amazing) bugs for instance. There are also generally a lot of shit games that run horribly to the point of nearly not being playable.
The mere fact that most new console games are updated with big patches quite often shows that they have their share of bugs as well (some of it is new content though but there are a lot of fixes in them as well).

Don't treat your PC like a shit and it will serve you good. If you put too much scumware in this bag (which is PC) then don't blame anyone but you.

And Torchlight is amazing, the only problem I had with it was slow loading of packed resources which I fixed all myself (such is teh power of PC gaming!). And then it was solved by a patch.

Well to anyone who complains about lacking uniformity, I'm thinking you are forgetting what the benefits are, and they far, far outweigh the downsides.

Ive "completed" DA, most of Torchlight, Witcher in the last couple of weeks without any hickups. The percentile might be a tad higher due to it being an open platform, but i hardly feel as if the crash is imminent everytime i boot up a pc game.

Might wanna have a look at your hardware/software to see if you have any known compatbility issues

Bugs are not exclusive to PC gaming, and console releases experience issues similar to those found with PC games. Worms Armageddon 2 for XBLA, despite going through the quality control that PC games are not subjected to went on sale with a myriad of bugs, some of which were incredibly annoying or game breaking. Even with the fairly recent massive patch, there are still problems. AI opponents for example are still completely moronic and suicidal.

You also have the MW2 javelin bug, which when fixed caused other gameplay issues. This is on a closed platform with quality control for content. There was also the full-game unlock bug for Shadow Complex, broken netcode for months with Castle Crashers, among others I'm sure.

There's Warhawk, Fat Princess, Socom, Metal Gear Online and other ps3 games that were absolutely broken day one online and required patches to fix things like stat tracking, matchmaking, and connectivity issues. Again, there's quality control yet each one of these games was released in what turned out to be a broken state.

The point is that while PCs lack uniformity, consoles still have many issues surrounding buggy releases, horrible initial functionality, and problems even with "uniform" hardware. Also important to note is that while consoles are made to a certain spec, they commonly undergo a dozen or more revisions throughout the generation. Some parts -- not unlike PCs, may be more reliable than others, or certain revisions may create problems that require patching, and vice versa. When hardware uniformity goes wrong, like the RRoD or some ps2 revisions(bad laser), it's much worse than PC component failures that can often be isolated and replaced.

tl;dr version - Even with hardware "uniformity" and quality control, consoles suffer from many of the same issues that PCs do. Installs, serious bugs, unreliable hardware, and OS updates aren't just for PCs anymore.

oh dood wait for the incoming mods(MP mod, MMO mod,) that game is extrememly mod friendly, it will be the best 5 USD ever spent on my end.

I love PC and console gaming. Though you learn that both have their ups and downs. PC will always be more buggy, but if you are a PC gamer who isn't stuck with the idea that the only PC games are made by console game makers too(EA, Ubisoft....) you find that there is a plethora of PC games that have no equal on consoles. That's because the open nature of the enviroment encourages innovation. The down side is that because there is no hardware standards or software standards gamers end up having to put up with software/hardware conflicts that occur far to easily.

Where as the console gaming is typically more polished in regards to errors and the singular hardware just makes development easier. The down side is that we only see a small filtered stream based on what the publishers see fit. This includes the idea of exclusivity, something that doesn't exist as much on the PC since Windows is the gaming OS.

I just know, if you want the graphics, you always go PC, if you want a better online experience over all, you go PC, as much as Windows Live sucks, I'd still take it over the console online anytime. The PS3 keeps surprising me this gen though, that thing is much closer in actual power to a PC than a 360 and keeps producing games I didn't think was possible on current gen consoles and is still wowing me with the quality of exclusives so far.

Torchlight is awesome because its nothing more than a facelift on the age-old awesomeness of Nethack/Moria/etc. (Rogue derivatives)

Its cheapness to develop, and purchase price, has nothing to do with consoles vs PC development costs, and everything to do with stamping out an age-old formula that publishers are too slow to take up the slack on when there are no modern versions of it available (see: Diablo II, release year).

That said... I'm gonna score Torchlight on disc, come Jan 5th... because I can't stand the idea of DRM on the PC, even though I'm fine with it on consoles. Wierd I know.
