There needs to be a couple of things for me to complete alot of achievement in games. 1: [b]No grinding[/b] : If the achievement is "Complete x level by having x weapon maxed to lv 1000 by being lv 100,000,000 and scoring 250,000,000,000 points in x level" Then i'm not doing it, unless it's doable and fun. 2: [b]No collecting [/b] : I would have never collected the flags on AC3 unless they would give me the maps, because then i'd see it easy, never cared for collecting mini things via game side quests, if it's not a main objective and it's not fun, then it's clearly not meant to teach you anything that makes you grow as a player, it's just so you could play the game more. It's essentially a cop-out by devs into tricking you to play more. 3: [b]No impossibly difficult ultra mega hard-on secret boss[/b] : Achievements that want me to beat the game on impossibly bullcrap levels or essentially NOT have a fun time doing it are not worth. 4: [b]No Secret Achievements[/b]: These are just stupid dumb and retarded reasons to either A: make you buy the book for a game (which nobody does), or B: Make you go online and research stupid FAQ's or walkthroughs about it... These are probably the biggest reason i don't care about achievements not only are people NOT EVER doing these legit but they are essentially wasting there own time trying to find something that isn't that big of a deal.
