Hmm... There is too much great games I play thus far...:worried:
The game that left strong impression for me:
*Xenogears (great RPG with amazing story plot and controversional story)
*Ace combat (starting from PS2 to above, ace combat series is very interesting)
*Armored Core (Mecha action games, full with upgrades and assembly mechas to get perfect setting)
*Mobile Suit Gundam Seed: Rengou VS Zaft 2 (Good gameplay and fun to battle with your friend)
*Prince of Tennis: Smash and Hit (Great playstyle and have much skills. Best game to play with friends)
*Need For Speed Underground (for me, it is the best racing game)
*Diablo 2 (since then, i haven't meet an action-rpg game as good as this is)
