Which are near impossible standard considering nobody knows at this point what will get bundled since so much has, even things we never thought would be, and also most of us realistically don't play our games unless it's some multiplayer get together thing.
That being said, couple of things I got that I hadn't seen mentioned on the thread. Probably won't meet the rigorous standards of people who are using to getting indie games for 10 cents each in a bundle and using vpns to fake being Russian or Brazilian to get commie or 3rd world pricing for the rest, but nonetheless.
Flyhunter Origins - $1.74 at 75% off. Nice looking 3d modern platformer that isn't all retro. Got good reviews, the few that are there. No I haven't played it yet.

Publisher has bundled stuff before (Kytt Underground, Really Big Sky) but on the other hand they also released Ironcast in March (great game btw) and have yet to bundle that.
Dovetail Games Franchise Collection - 80% off at $14.99. I realize that's too rich for most people's blood here but I'll throw it out there anyway. Has Euro Fishing, Microsoft Flight Simulator X, Train Simulator (which most people have) and then 3 different DLC tracks for Train Simulator that aren't the usual ones that have been in bundles or cheap packs.
Also the Warhammer 40K Dawn of War Franchise pack at Gamersgate for $7.28 on the Russian store is a good deal if you missed that on prior sales since it includes a whole bunch of stuff, but that does require a bit of minor hoop jumping.
I bought a few other things here and there but a lot of stuff I just don't mention because the standards here are basically if it's more than 3 cents GTFO
(not literally; that's hyperbole but you get my drift) so a lot of times I just find little hidden deals here and there and don't mention it.
