Finally got the Xbox Series X !

my brother in law got me this as an early birthday gift , I was deciding if I wanted this or a ps5 but tbh there are quite a few games that are backwards compatible i wanna play so I settled on this. I havent really played any games or owned a console since the ps3 when I was a kid. he also got me a copy of cyber punk. what other games should I get? my all time favorite games are old. number 1 would be oblivion, and I had the chance to play some remastered so ill definitely get that. another game i love in age of empires 2. anything open world, or horror or good indie games you'd recommend?
