Ill assume you're talking about Souls games ? Vs Rogue likes ? ... One is only about getting good and learn patterns for that boss without having to do much to face it again... the other is about doing a whole run again and again, counting on luck to attain good loot and than having the opportunity of learn its patterns to eventually do another run, get lucky again with loot and finally beat the boss.
I liked returnal but it is very repetitive as every rogue like I played is, and I enjoy it for a few hours, but not enough to pay full price.
Saros probably is a very good game on its own, but unfortunately trapped in a not highly popular genre, nothing wrong with this btw. Not every game has to be a blockbuster for the masses.
Ill definitely play it down the line probably on Psplus next year. I dont spend money on rogue likes anymore.
