Steam doesn't seem to have any good sales this weekend. Jamestown is a new game that _looks_ really pretty, but it's a Shmup, which i enjoy on occasion but aren't really my thing. They're also advertising Terraria, though it isn't on sale, which i didn't originally think was my thing despite looking like someone combined Minecraft with a 2D platform game using a 16-bit Final Fantasy skin. However Tom McShae gave it a great review and ranted about it on the HotSpot podcast for awhile, so i'm actually thinking about spending a whole $10 on it :)
On the other hand, now that shelleycat has heard that Jonathan Coulton did another song for Portal 2 she wants to hear it, but i don't want to listen to it until i've finished the game. I've been holding out for a sale on the theory that i'm unlikely to manage to do the co-op mode with anyone. Do i even know anyone who's planning on getting the game but hasn't done the co-op already? I know jmpava was planning on doing it with coraa, and i know that stormfeather got through the game ages ago. Anyone else? So i'm not sure if it's worth paying $50 for just the single player, but with shelleycat urging me on i'm kinda tempted. (And no, i can't really play it with her, even if it didn't make her motion sick she says she wouldn't be very good at it.)
Edit: So it seems that despite my initial impressions, neither stormfeather nor jmpava have done the co-op yet, so i think i shall use the _potential_ to play co-op as an excuse to get the game :)
Also, i forgot to mention that GOG is also doing a sale on Strategy First published (not developed) games this weekend. It's quite a wide variety of stuff.
