Skyrim is considered one of the best games of the decade whereas doom is just a great reboot and an excellent shooter. Get both eventually but go with Skyrim first
Skyrim, although Doom is great, you pretty much just have the one thing to do "Kick A$$". Skyrim has a pretty large world full of exploration, lots of different characters to meet, things to do, lots of potential
Doom is an amazing FPS it's a breath of fresh air after years of terribleremakes skyrim is awesome as well if you've never played either I'd say Skyrim.
Skyrim. More content. More to do. see. a lot more replayability.
Its what BotW should have been more like tbh. Huge open world but plenty to see and do with sidequests with their own story.
Its pretty much LTTP mixed with Majoras Mask mixed with BotW.
Oh and the musics awesome too. Much like most of Zeldas
I had 'Skyrim' years ago on the 360, and for whatever reason I could never get into it. I did just pick up 'Doom' on the Switch however, and I can tell you that it is a blast!
They're very different games, if you want a frantic awesome violent experience with face-melting music then go for Doom. If you want a 3 billion hour long adventure with magic n swords n shit where you can essentially do whatever you want a big ol' fantasy world, go Skyrim. Have fun!
