I am very into RPGs so these two are mostly the deciding factors. I also like simulation games but it really depends on the game. A simulation game like Animal Crossing, for instance, appeals to me. However, games like the Sims do not.
RPGs are the majority of what I play. Most of the time they’re JRPGs, but recently I’ve been enjoying western RPGs too. It’s a diverse genre filled with a wide type of games while usually having an emphasis on story and characters. If I’m burned out on turn based RPGs, I can just boot up an action RPG and get a different experience.
