so you only cheat when there is less then 1 players????
anyhoo, ill play a game until i get bored of it (then play it alot when i recover it a few years down the road eg. i just started playing dk64 again). If i get bored of it after beating it once or getting 100% or if i get bored after beating it 5 times it doesnt matter. I stop when ive lost intrest or when a sequel comes out. Id say some of the games i havnt gotten bored of yet are NFL Street 2, Animal X-ing, SSBM (which will be replaced by Brawl), and pretty much any mario title. Theres others but i dont feel like listing them.
Hmm, i usualy tend 2 juggle between 4-6 different games which usually takes a while 2 beat just 1, but i can't keep playing 1 game for days, just makes me get bored of it after a while, but I do try the best I can 2 complete the game at 100%, especially if you get unlockables or some special ending you cant see unless it is 100% completion, (example: Final Fantasy X-2)
i personally, try getting everything i can as i play the game. for example, when i was playing MP3, i collected all the upgrades, except for two. so i had 98% and i finished the game at that. i thought i would jus go back after the credits........but little did i know that i had to start all over again in hyper mode. LOL
In the top notch games Like Metroid, Mario etc. i quite often aim to reach the 100% however in some third party and not so good games i just plan on completing them
