We're probably due to try and start creating a list of the important/awesome/creative/amusing games in the indie PC world. If people are interested in listing games they think the rest of us should check out, I'll try to keep the thread up to date.
As for myself, I just checked out The Wonderful End of the World and Aquaria. I'm a little late to the party on both.
TWEotW is pretty much a straight up Katamari clone without the budget or the high doses of charm, but it scratches the right itches. The video game level is pretty awesome.
Aquaria is extremely beautiful; I think I'll be paying for the full version.
I'll also remind folks to check out Passage and The Marriage. I think they're both very important games that folks should check out. Neither will require much of your time.
Is anyone else playing anything interesting on the indie game front? I normally don't hear about these sorts of games until I see them on some random list or blog, so I'm apt to miss a lot of them. Any recommendations would be very welcome.
