I bought over a dozen promotional games, with high discounts on several old games, Cities: Skylines-90% for only $2.99; Darkest Dungeon-92% for only $1.99. Also bought a promising HoMM-like new game, Pennon and Battle.
I got Cities and the Tomb Raider reboot trilogy (with all DLC) for $13
Gearbits Mafia Trilogy Dave the Diver
I’m enjoying the hell out of Gearbits. It’s an indie mech shooter with Gundam aesthetics and fast-paced action like Armored Core for a base price of only $10.
Factorio Space Age, but it wasn’t on sale.
Slime Rancher
I would say definitely worth the 2 bucks. I wanted something I could play without having to pay attention to story, so it seems to fit the bill pretty well.
