TIM came with the first computer my parents had bought in five years. Before those glorious days of the 66Mhz Pentium we had a few 286 (I think? Maybe one 386 later on) CompuAdds back in the 80's. They weren't good for much except typing and playing Battle Chess. I mean, I played Wolfenstein and Doom at friend's houses, and then there was that Chips game and the obligatory 'worm' and 'pac-man' clones, and of course there was the cat who taught me to type in grade school, and Oregon Trail... But really, TIM was the first computer game I played at any length. Before that I had never had a computer in the house capable of playing games. Games to me existed on the consoles; Atari, NES, etc.
I've been playing the crap out of Return of the Incredible Machine, but the fact that the puzzles are almost all clones of original TIM2 puzzles is kinda sucky. There's a "puzzle pack" for RTIM that I've yet to install. Not having to mess with DOS emulation makes RTIM fine by me, though.
I don't like Whizzball much, it's too linear. More like putting pieces of a puzzle together than coming up with any kind of creative solution that could actually be unique.
