1. StarCraft: Brood War
My god, this game is awesome. Still to this day, I play a couple of games online every week.
Can anything be so simple yet so perfect? No handheld platform is complete without Tetris, the ULTIMATE bathroom game. Yes, this last statement is a little gross...
3. Half-Life: Counter-Strike
This one almost killed my academic career. Played almost every day at a local LAN house during my senior years. Good simple times!
4. Street Fighter II: The World Warrior
I've entered some pretty nasty arcade rooms to play this game.
5. Sid Meier's Civilization
Hours and hours irrigating land and building roads.
6. Mike Tyson's Punch-Out!!
This game has little to none replay value, yet, I've played it countless times. I still think Mr. Sandman is tougher than Super Macho Man.
7. Metal Gear Solid
Played this one over and over and over.
8. Maniac Mansion: Day of the Tentacle
Perfect. Sometimes I wish I could erase it from my memory, so I could play it for the first time again.
9. Mega Man 2
To me, the best in the series.
10. Doom II: Hell on Earth
That last level was impossible though.
