you can absolutely have all three!!! as for games, felix started when he was really young streaming minecraft and roblox and then fortnite, then just worked his way through things. now he mostly streams team fps but he plays a bit of everything, and he's getting into mmos a little...

we can combine them in any way we like. for example:
- dragged back to high school as an assistant track coach as a favor since he went to uni on a running scholarship, ends up giving izuku pointers
- they get to talking about jobs and stuff, felix mentions they look for part-timers sometimes at the coffee shop he runs, so he should apply
- izuku gets the feeling he's seen felix somewhere before all this, realizes he used to watch felix's streams (or maybe still does)
