I bought quite a few cheapies, among them:
Some DLC for Magicka
Resident Evil 2 Episode 1
Fable Anniversary
Myst: Real Masterpiece
Sonic The Hedgehog 2
Some DLC for Sonic & Sega Racers Transformed
Sonic CD
E.Y.E. Cybermancy
Ori & The Blind Forest
Wolfenstein The Old Blood
I haven't tried Fable, Wolfenstein, Myst or E.Y.E. yet but I can say I think Ori and the Blind Forest is very good indeed. Maybe a little cutesy but good gameplay.
I also like and have been playing Child Of Light but I bought that in an earlier sale.
I bought Magicka in a sale last October and only just got round to playing it. Played the tutorial and first level and liked it so bought some DLC. I wish I hadn't. Cos I got to almost finished level 3 (of 12 levels) and got stuck, it suddenly got hard and I became terribly frustrated with it and gave up. Ho hum.
I am looking forward to playing the (rather short, apparently) Wolfenstein extra.
I also bought Beyond Good and Evil in the GOG sale.
I bought Outlast some time ago and didn't like it at all I'm afraid, all dark, murky and indistinct and just too damned difficult for me.
Maybe my advanced years are taking their toll, lol, but I still do ok online and with most other games. Maybe I need to practice Magicka more but just like 'sensible' software, if I don't take to a game within the first few hours then - pfft! That's it, goodbye.
