I used to be more obsessed with finishing games 100% than I am now. All the original Crash Bandicoots and Spyros and a whole host of other games I had to finish entirely! Even games like Pokemon; I finished Blue and Gold 100% (captured all the Pokemon) because in my view the games weren't complete until I had that 100% notification!

Not to 100% mostly. I went through stage a few years back when buying too many games to complete. Burned out and nearly went off games lol.

Regrouped, started completing them and buying less.

I do remember getting 100% complete on Donkey Kong Land on Gameboy a day before 2nd on came out, that was fun. I hadnt played it for months and was missing one token, tried the lvl and fell off ledge but fell into the token as was secret lvl below, happy times. This was before i knew about online game help....

Also - kids seem to have more cash these days then when i was a lad. Before in yesteryear you could spend time getting 100% complete as you couldnt afford another game for like a month

Usually I wait for bug fixes to be released, not too biased reviews to be written, other gamers to give their verdict and prices to drop before buying a game, so I almost always get what I like, but in a few cases I couldn't continue playing or even start them due to bugs or HW incompatibilities, luckily they were from bargain bins, a few other times I stopped playing because for my tastes they were crap and of the most recent games I stopped playing I'm not very willing to continue only one, Temple of Elemental Evil, that I didn't reinstall when I upgraded WinME to Win2000, because I feel it would be too inferior to the others I want to continue and to Planescape: Tormen I'm currently playing, but I'll need some time and reading some walkthrough up to where I left them to avoid restarting from the beginning, as too much time passed and I lost the thread of their plots/quests.

And usually I like to play 100% of the games I like, without skipping subquests, and exploring levels completely (obviously this helped me getting lost in Morrowind )

I usually just end them but don't bother getting 100% with extras, optional quests etc.

I would say in over 50% of the cases I finish them. For FPS even up to 95%.

I finish games in terms of playing to the end of any SP element. I don't finish them in terms of getting every possible point/trophy/achievement - i.e. I'll finish Uncharted or KZ2 but I'm not going to replay them until I get every little thing.

Usually I finish whichever game had at least a 80% rate that I agree, I just remembered one reason I'm disappointed with ToEE, it has little to do with the game itself, not a masterpiece, but not bad: I like RPG's very much, but I' not an expert and I never played a bard before, and generating characters, I didn't know I should have discarded the bard until Charisma was high enough, so I discovered after completing more than half game that my bard was nearly useless, not having access to its top level spells and abilities. Most of the biggest battles are tough, but not impossible, but in the big showdown with Hedrak having a crippled party member isn't the best beginning and anyhow the thing disturbs me even when it isn't a real trouble, just those things like the thin wire in Trinitron CRT's that not knowing of it I never noticed before, but as soon as I knew of it, I focused my look on it whenever I used one. If I ever reinstall it I think I'll go to the Inn, leave my bard and generate and hire another and level it up with casual encounters until it's decent before continuing the temple quests.

i complete most games i own, all though some take me over a year as i mainly play online on Gears of War and Call of Duty, but eventually i finish most games

edit: i just do the main games though, i dont go for 100% or anything, i have a life outside my consoles you know, but yeah ive never done a 100% job intentionaly, i never have the time, i also have over 150 games now
