Steam

With my new laptop up and running, I am happily playing several Steam-based games:

Dust (I am pretty impressed by this. It is a platformer, side-scrolling game with really nice visuals, voice-acting and insane combo options)
Dungeon Defenders (yet to start this under Steam, but played it extensively under Android)
Dota (downloading)
Wakfu (played on my old 32-bit box, but Steam refuses to start the game if you are running 32-bit arch. With a 64-bit arch, it will start)

I also have some extra games that I’m not playing or stopped playing:
Bastion (tried it and it is interesting, but I’m finding it really difficult to get into
Dungeon Hearts (slow and laggy)
Ravensword: Shadowlands (an interesting 3D, but very little customisation options)
Toribash (Appeal wore off very quickly)

I am also playing two non-Steam-based games

World of Warcraft
League of Legends

Although, I have them tied into the Steam framework so I can start them up via Steam and grab screenshots, etc.

I have also looked at Fraps and Kazam — two screen recorders (Fraps for Windows, Kazam for Linux) and both perform pretty well. Fraps performs great, I got smooth high-quality video out of WoW. Kazam, I am tweaking settings. It also generates good-quality video, but I need to play with the framerate and encoding settings. Look out for some uploads at some point in the future.
