Lizard Dude sets trends.
All games that are currently unfinished are this way- unless otherwise noted- because I for some reason lose interest for large periods of time, then come back and either start over or realize I'm still stuck.
Off the top of my head:
NBA on NBC- Best basketball game I have ever played. Which isn't saying much. I still have like, five teams to beat.
Crash Bash- Come on. It's Crash Bash.
Tony Hawk's Pro Skater 4- Still haven't gotten all the achievements yet.
Top Spin- This game takes forever. I would win a whole match, the opponent scoring like, two points, and it takes an hour to finish a tournament. Geez.
Burnout Revenge- Just lost interest for some reason. Kind of repetitive. About halfway finished.
ESPN NFL 2K5- This game takes forever, too. You need to play like, a million games to unlock all the Crib Achievement things.
Final Fantasy VII- Yeah I played this game for like, an hour.
Final Fantasy IX- ^
Final Fantasy Tactics Advance- After pouring hours and hours into this game, I still can't get all 200 missions done. I always end up throwing away a vital item
New Super Mario Bros- Of course I've beaten this game. ...on one file. I promised myself I will not be done with this game until all three files are three-starred.
Meteos- I got pretty far but then it got boring quick. I still have stuff to unlock.
Metroid Prime Hunters- Haven't beaten the final boss yet
Final Fantasy Dawn of Souls- I'm stuck on Final Fantasy I. I don't remember where. I never even started Final Fantasy II
The Legend of Zelda Oracle of Seasons- Stuck on the final dungeon
Prince of Persia Warrior Within- I got pretty far but never finished it for some reason
Animal Crossing Wild World- Is it even possible to beat this game?
Mario and Luigi Superstar Saga- It broke before I could finish it
Every Pokemon game I have- I have never caught all 150/250 whatever. Except I seem to remember doing it in Red once. So not Red.
