Adventure- hands down the best. Still enjoy it to this day- half notalgia, half fun. I believe I was 4 when I started playing Adventure. Still remember the very first time to this day! Pitfall 2 oh so close, but Adventure is tops. My top ten:
1. Adventure
2. Pitfall 2
3. Pitfall
4. Raiders of the Lost Ark
5. River Raid
6. Keystone
7. Warlords
8. Bump & Jump
9. Q-Bert
10 Superman
Any votes for Fast Eddie??
