Void Marauders: Purchased while drunk. Xcom but you're space pirates. Receiving regular updates. It is still in crude early access. I believe it to be the efforts of one person.
Dread Delusion: Purchased while drunk. Incredible art direction. First person RPG. Has a team working on it. Still in early access, but shows a good level of polish.
Synthetik 2: Bought this one sober based on the strength of Synthetik 1. Top Down Shooter. Has a full team working on it. Shows a high degree of polish.
ADCA: Bought sober. Single person working on it. Half-like with cell shaded graphics. Extremely irregular updates, currently notably incomplete but with a high level of polish.
