Depends if I'm being orally pleasured in the meantime. If not, I adpot a strict zero-tolerance policy.

Well it all depends.

I did find the Deus Ex loading screens annoying, but in many cases they gave me time to recover my thoughts and re-organise my mind for another effort if I died, but for progressing the story it gets annoying

It isn't really the loading screens that are the problem for me, but unskippable cutscenes or very frequent delays between scenes. Gears 3 actually did this a lot. My friend and I have been playing on insane, and doing a bit rubbish, so dieing a lot. The issue is that they put the checkpoints behind these unskippable cut scenes and sections where you are forced to walk slowly, and that is really infuriating, that is just bad game design as opposed to technology issues, and Gears is certainly not the only game with that issue

Exactly. I don't mind the loading times in GT5 since you race for a long time in between and you can instantly restart races without loading, a feature every driving game should have.

I hate it in rpgs when it has to load for every single screen or building you go into and out of, no matter how short. DA2 was horrible with all the loading. You walk five seconds, you load 5 seconds for most of the game. In some games I get hesitant to peek inside buildings because of this, I rather keep walking to the next objective.

When you are just going forward in a corridor it doesn't really matter when you get a little break in between hectic fights. Even better to hide them during pre-rendered cut scenes. Although it does affect my play style. I rather stick to a tried and true method and/or easier difficulty levels if death means a long loading screen. I played Deus ex on pc so I could experiment all I wanted with frequent reloads to try different things. I loved playing games on pc back in the day when developers prided themselves on adding quick save and quick load to their games.

I wish all games would have a resume mode. GT5's spec 2.0 resume for endurance races is perfect. (Still a long load though) It takes way to long to boot up a game and get back in the action.

I don't mind as long as they don't have one between death scenes. In the past, I'd endure a long loading screen and then die, only to have to face a loading screen. On a tough boss, I'd spend more time looking at the load screen than I would playing the game. Unacceptable.

The worst loading screen nightmare I ever played? Death By Degrees on the PS2. WTF, Namco? Everything you did caused a loading screen! Sometimes you'd face a ten second load for a five second cutscene.

Hate loading times to death. Anything past 3 seconds is torture.

If you can't be arsed to go past a 3-5 second loading screen that does not bode well for almost all new games with any mass of content... Loading screens on consoles are getting a tad ridiculous imo.

I guess I'll have to nuance my position a bit. Uncharted 2 has very long loading times when you start it up but once you're in the game there's none. That I have absolutely no problem with so I guess I'll side with KylieDog and say that it isn't so much the load times that bother me but the frequency at which they occur.

Depends on the game. When i had Civ 4 on a crappy computer it'd often take 15 minutes between turns to calculate the AI moves.

More than 10 seconds is too much. Mass Effect 2 on PS3 was brutal.

20 or 30 minutes :P

Well, it depends on the game, I wouldn't want to wait more than 20 seconds in a game like God Hand, but I'm fine waiting 20 minutes in a game with very big areas that will take me a long time to get past until I see another loading screen.
If I get 20-30 minutes loading screens very often, I'd probably think something's wrong with the console or PC.
Never got anything that long though... the longest ones I've experienced were in MGS4 waiting for like 3 minutes to install the next act in the game. Those didn't bother me at all since they were so far away from one another.
Heavy Rain seems to have sort of "long" loading times too (like 20 seconds) but they don't seem to bother me.

I can't think of any game with annoying loading times (from the ones I've played)...

I think loading times will be way shorter next-gen.
