FWIW, I've had more successes than problems with games.
11 games I'd have bought anyway [1] (mostly RPGs), 1 failure (The Mandate. Should have known, overly ambitious) 4 that are way overdue but still active (Star Citizen, InSomnia, Popup Dungeon and After Reset), 3 that are still in planned development (Vigilantes, Stygian and D:OS2) and only 2 games I didn't enjoy at all and normally wouldn't have bought (Jagged Alliance: Flashback, Satelite Reign)
[1] Wasteland 2,
Shadowrun Returns,
Pillars of Eternity,
Antharion,
Balrum,
Torment: Tides of Numenera,
Balrum,
RimWorld,
Lords of Xulima,
Blackguards,
Shadowrun: Hongkong
edit: And 100% sucess rate with tabletop/card games
