Rise might be the best place to start from a tutorial standpoint. I’ve replayed MHW many times and I feel like even knowing what I’m doing it takes hours before I’m actually in the game. Rise came out during COVID and was half-released when it did which meant they didn’t pour as much time into over-extending the intro. The downside is Rise is exceptionally mechanically stacked for a MH game, so it may take a little time to get started from that standpoint. But also, I would discover new weapon mechanics 70+ fights into using a weapon also, so don’t worry about trying to learn it all up front.
