Retro-styled platformer. Simple mechanics explored with great depth and inventiveness. Also, great music.

Joyful, ridiculous Oregon Trail spoof. One of the funniest games I've played. Also, great music.

Deceptively simple puzzle/roguelike. Short games and small playing areas conceal an absolutely huge amount of tactical and strategic depth.

Abstract train-planning puzzle game. Beautiful visual style and engaging mechanics.

A bit Mega Man, a bit Castlevania, a bit Duck Tales, entirely brilliant. Also, great music.

Really interesting, brain-bending first-person puzzle game.

Great narrative RPG with a fascinating world and compelling story. Unfortunately a bit broken in its base state; make sure to get the fan patch.

Maybe the deepest and most satisfying puzzle game I've ever played.

Probably the best Star Trek game ever.

Grand strategy in the age of steam and colonisation.
