Worthwhile games:
1) Half-Life/TFC/CS - Spent almost 3 years clanning in TFC made the $40 I paid for worthwile.
2) PSO for Dreamcast - Probably logged about a few hundred hours while it was free to play online.
3) Soldier of Fortune II (PC) - another few hundred hours here for its online play. Paid $50 tho.
4) StarCraft - another few hundred hours put into this game.
5) Final Fantasy III (SNES) - probably 200-300 hours, although the game was $69.99 when it came out.
Games that wasted my money:
1) Dark Age of Camelot - $20, clocked in 15 minutes, I kid not.
2) Mortal Kombat: Deception CE - paid $60, clocked in 2 hours.
3) Time Crisis 3 (PS2) - paid $40 w/ Guncon, clocked in 2 hours.
4) StarFox Adventure (GC) - paid $50, only clocked in ~3 hours over 2.5 years.
5) Soul Calibur II (GC) - paid $50, clocked in 5 hours at most.
