I'ma make this a recomendatio thread too...
I'd really recommend Inertial drift to anyone who likes arcade racers, it's only 5 euro but it's a very unique drifter with a unique control style that takes a while to fully get used to but it's ended up as one of the best drifters I've played and I've played many. Very short campaign but the modes are super fun and the trophy list is pretty cool too. It's up there with CarX Drift racing online but where that game lacks cohesion this game is polished and packaged nicely.
Also, I'd recommend Brotato to anyone looking for a rouglite, especially someone who likes Vampire survivors and to that matter NERD Survivors too which is a close imitation and a little more difficult but very much fun. Army of Ruin is another fun one but not of the quality as the rest, it feels more like a mobile game with star ratings for levels, solid 7. And anyone looking for an old school shooter in the vain of F.E.A.R or similar 00's games I'd say go for Tarpang2 when it's back on sale if the sale it was on has already passed, really solid title that brings back nostalgia for the older FPS games.
^All super cheap games with way more hours of value in them for their money.
