I don’t have a lot of experience with roguelike games. Before I even knew about the genre I played quite a bit of Spelunkey. As someone who loves Super Mario Bros I thought that game was great. I recently found Vagante and am having a lot of fun with it. It gives off Spelunkey vibes, but is more traditional fantasy.
The worst thing about a live service game to me is that they only work when you can connect to the official servers. Many live service games have shut down and there is no offline mode to continue playing. Sometimes you still pay full price for these games. Sometimes games like The Crew, shut down after you spent money to play it and then The Crew 2 comes out so you pay full price for essentially the same game and the first one doesn’t work anymore.
