I'd like to think of Multiwinia as the light side of gaming, in a way, because it's everything that the large corporations isn't. That's to say, it's an original concept which we haven't seen since... well, since DEFCON really, and before Introversion stepped up to bat, since those crazy games like Day of the Tentacle back in the day. I think the dark side of gaming is really the "make games for no other reason than profit" which leads to one of the following formulas:
Grind + Spiders = Grind + Slightly larger Spiders
Guy with gun + Other guys = Dead guys
And the Dark Forests aren't dark. You want Dark? Try this out for size:
(This is on a map that someone's made for Human vs. Futurewinians, which means there's the other CPU that got shafted for them using retribution)
Futurewinians used Dark Forest!
Pinky: Well thats fine, it didn't kill many of my units, and now it's harder to capture my spawn.
CPU(Green) used Meteor Shower!
After the meteors had stopped falling, it became apparent that they had all somehow missed my forces standing in the very center of the target range. The meteors had, however, set the Dark Forest on fire.
