Since MC is going more towards the path of an assassin/ninja, it would be cool to have this game, but if you want to develop it step by step, it's better to go for Overwatch, which is a universe where the characters are stronger than Valorant. Of the games you recommended, league of legends, for slow development, DMC for fast development. Just don't forget that if you choose DMC, it's inevitable that you'll get involved with demons, both Mephisto and Belasco, because he's half demon.

Author san wouldn't you rewrite history?

please add the world of Mercenary Enrollment

The pace of the story is good, but it would be better to do a reboot or edit the chapters so the story is more fluid.

Please continue

You could make the spider appear to MC, and he could study it with Kryptonian technology, and replicate more spiders, to have the spider family, since MC's memories would be unlocked

You can continue with his and Kara's romance or with someone else, no problem, but let him follow the path of a mercenary/anti hero
