What games can you recommend that didn't get the appreciation that they deserved?
I've been recently been thinking about Arkane Studio's Prey which is a immersive sim, with a pretty good rogue like dlc, that probably has one of the strongest hooks of any game I've played. If you liked Halflife, System Shock, or Deus Ex it's definitely worth a play.
Are there any titles that might not have been commercially successful that you feel everyone should give a shot?
I picked it up on sale after watching Fury Road, which in turn I put off watching for years because I really like the first trilogy and did not want to have that memory tainted by some cash grab Hollywood sequel. Boy was I wrong about the film, and I was equally blown away by the game, to a point I felt really guilty getting it for 10 bucks or so. I really, really wish there was a multiplayer, though.
Mad Max is honestly probably one of my most replayed and enjoyable games that I own. If it wasn't for Sims 3, it would have the most hours in my Steam library. For me there's something just so cathartic about driving around the wasteland looting scrap and beating up warboys lol. And then getting some mods/trainers involved and exploring the dev areas out in the Big Nothing is great too. I've gotten some really great screenshots out of that game.
My biggest disappointment in it is that my favorite zone of the map only has one mission, but that mission is great. Apart of that its cool riding cars in the desert.
