Thanks! I used to love the Activision games, which were always superior to the regular Atari ones, until the newer Atari ones like Vanguard and Ms. Pac-Man came out. Well, some of them were stupid, like Laser Blast, which seemed to depend more on luck than anything else (the laser shots were so fast that they were almost impossible to avoid).
Keystone Kapers was excellent. Very hard for me to get past a certain level. And I had tons of fun mapping out Pitfall!. River Raid was great, until it broke. And with Ice Hockey, I think I once beat the computer 45-0 or maybe 47-0. Kaboom kind of frazzled my nerves as it just got too fast.
And with games like Skiing, Sky Jinx, Barnstorming, Stampede, and Grand Prix, the problem was once you learned the pattern to get a score high enough to get a patch, you lost interest in the game.
And StarMaster was fun. I sucked on Star Raiders, so I had more fun with Star Master, as it was easier to beat.
