At one point I had been playing GTA V online pretty consistently when I had a cheater start targeting me. It was pretty frustrating and after 30 minutes of that I gave up and closed down for the day. I shifted my attention to other games after that. I definitely get that they want to stop cheaters - cheaters ruin the fun for others. It’s a shame that the new anti cheat has made it so that Steam Deck players are stuck unable to play online.
Over the years I’ve gotten rid of every console except for my Nintendo consoles. Sure their hardware is not cutting edge but I don’t really care because I always enjoy myself when I play my Nintendo consoles.
If you want the 202[3/4/5] version of COD at 4k 60fps then an Xbox is probably more suited to you. Nintendo just isn’t going after that segment. The variety is a good thing.
