I can think of a handful of games that, despite being games that I’ve enjoyed, never really became part of a “genre”. Do you have any like this, and if so, which?
Are they games that you’d like to see another entrant to the genre to? Would you recommend the original game as one to keep playing?
Maybe SimEarth.
This simulates a tile-based planet map. Animals grow and evolve, and things like atmospheric concentration and other aspects like surface albedo can be altered. More a toy than a game. Had a lot of fun playing with the levers.
1990 release – it’s still playable, though it’d feel pretty ancient and will not be very beautiful.
I haven’t played SimLife or Spore, and there might be some similarities there.
I’m not aware of anything else that’d be comparable.
EDIT: Liquid War. This is open-source and part of the GNU project. One has a map with some areas closed off and some open space that liquid can flow through. There are two or more “blobs” of liquid of different color; each is attempting to destroy the other. Your blob is attracted to your mouse cursor. “Moving into” a pixel of the other color eventually converts it to your own. If two liquids meet in a bottleneck, they tend to stalemate. One wins by getting liquid on multiple sides of the opponent’s liquid, so that one can move one’s own liquid from multiple directions into it. Maybe a bit closer to a tech demo than a full-on game. I wouldn’t call it mind-blowing, but it is free and as far as I know unique, and I had fun with it.
I never went very far into SimEarth (I remember getting a bunch of maxis’s simstuff in the 90s, and not having the patience to really get into some of them back then).
However, I did play Spore during its prime. It’s very shallow, on all levels. Don’t expect any kind of simulation in there, especially not physics or even basic biology and evolution really.
Its whole gameplay loop : design a beast, eat or make friends, be a tribe, fight or make friends, design a town and vehicles, fight or make friends, design a spaceship, fight or make friends and try to reach the center of the galaxy because I don’t know.
You can manipulate planet atmospheres in the space phase, but there are no variations : you can basically make planets “suitable” for life, and all life in the game needs the exact same parameters. There is zero room for experimentation and everything is basically just as efficient as everything else.
I almost forgot about SimEarth. For some reason I was allowed to play it in grade school computer lab. I wish they would remake it so I can recreate my sentient cephalopod uprising, except with graphics that aren’t complete ass.
I never played SimLife. But no, Spore is really not like SimEarth at all. As the other person said, Spore is disappointingly shallow on all levels.
Liquid War was awesome. One of my favorite things about it was that you could make your own maps using black and white bitmaps.
