Personal favorites so far from a member of the peanut gallery who did nothing but play video games from 1981-1990:
ROUND 1
2. biggamer3  Super Mario Bros. (NES)
- Still remember the look on my parents' faces when they woke up and saw their 9 & 8 year old children still playing this at 8am after their first ever all-nighter.
3. Andy Dufresne - Tecmo Super Bowl (NES)
- Played a ton of the original and this, 4-person arcade version was sweet too.
ROUND 2
7. wazoo11 Street Fighter II (Arcade)
- Remember how fun this was in the arcade and people lining up to play it and marveling at the ones who had mastered it.
8. Yo Mama ET (Atari 2600)
- Worst game easily, I remember how much this game confused us when we tried to play it and how pissed I was when I found out it just didn't really work.
10. madshot31 NHL '94 (Genesis)
- Great game, still remember playing the first one for hours... "The fierce fish win the cup!"
13. pollardsvision Doom (PC)
- Played this a bunch Frosh year of college when we discovered the magic of the school network for multiplayer.
ROUND 3
1. pollardsvision Mike Tyson Punch-Out (NES)
- Great arcade game and great port, I still have a PCB for a spin off game that I wanted to use to build a hybrid cabinet mod that I won't spotlight even though I'm sure it won't get picked.
ROUND 4
4. larry_boy_44 Donkey Kong (Arcade)
- One of my earliest memories of playing an arcade game, I was never into Pac-Man that much.
13. pollardsvision Pro Wrestling (NES)
- Glad to see someone else loved this game as much as I did.
ROUND 5
3. Andy Dufresne Star Wars (Arcade/1983)
- Not sure how many visits to the arcade it took before my pulse stopped jumping up when I would see this game.
9. Slax Mega Man II (NES)
- Fun game and sort of a puzzle to figure out the right method to beat the bad guys
12. Mario Kart Dragon's Lair (Arcade)
- My strongest arcade memories revolve around this game, probably my favorite ever and I own a string of all the ports on several systems over the years.  Currently play on the iPhone with my kids sometimes.
13. BlueDredSo Super Mario Kart (SNES)
- Didn't have this but Mario Kart Wii is a blast.
ROUND 6
2. Mario Kart Gauntlet (Arcade)
- Great arcade game and playing along with (against? for food) strangers/friends made it more fun.
6. bmarks6161 Quake (PC)
- Probably the last video game I played with any regularity.  The rail gun kicked ###.
ROUND 7
4. Yo Mama Contra (NES)
- Awesome game, would sit for hours playing through, and who doesn't know UUDDLRLRBAStart?
8. bmarks6161 Double Dragon (Arcade)
- First? and one of my favorite team beat-em-ups.
ROUND 8
2. Mario Kart Phantasy Star (Sega MS)
- Phantasy Star II made such a big impact on my brother and I that I even referenced it in my best man speech at his wedding.
11. Andy Dufresne Pitfall (Atari)
- My very first video game, got it with the 2600 for Christmas.
ROUND 9
10. larry_boy_44 Excite Bike (NES)
- Very simple but very fun
ROUND 13
1. pollardsvision Blades of Steel (NES)
- Awesome game and fonder memories that the Sega NHL series.  Placed in a BOS tourney at a McDonald's by my house and won some free gift certificates.
There's a few more games that really stand out in my mind and looking forward to if and when they'll get picked.
