Well, let's see, the games I've been playing a lot recently have been:
Etrian Odyssey IV (My first EO game, mapping everything out manually is way more fun than I expected)
Gradius V (Simply awesome)
Nano Assault EX (It's pretty good)
Space Invaders: Infinity Gene (I swear, I WILL finish Challenge mode one day)
Garry's Mod (Mostly Art of Parkour and Sandbox)
Knytt Underground (I finished it, the ending was pretty lame, albeit clever, and it's more about the journey, anyway, as is actually stated in-game)
Metal Torrent (Yes, even by shmup standards, it's short, but you're supposed to play for score anyway. Also, the three bosses only LOOK the same)
Maybe I play too many shmups? Nah.

Oh, and that Ugly Baby game that was in the Potato Sack has been getting rather frequent updates lately. It's almost a completely different game now!
