Trying new games has lead to all sorts of great games. In my group, we have a good mix of people who like to run a game as much as play one. We didn't want one person to get stuck running a game for years, so we decided to do "seasons". We have a few games that we rotate through ever couple of months. We change games and genres, so everyone gets something they love. When a game comes around again, we pick up where we left off. Right now we're playing D&D and a superhero game. We're looking to add some cyberpunk. Our superhero game is actually a mix of different games. The premise is that we're a team of superheroes trying to solve a multiversal problem. So we play different versions of our heroes on different worlds, each world a different game. When we solve part of the problem and learn something new, we progress to the next world and get a little more powerful. It's a ton of fun and we've tried games that most of us have never tried.
We also take a little break from regular games from around Thanksgiving to New Years, as holiday schedules are rough. So we call that "One Shot Season". If someone has a game kicking around they haven't been able to try yet, or wants to try their hand running something else we play, we do a one shot. Whoever can make it joins the one shot and we try a new game. We found some great games that way too, that we probably wouldn't have tried otherwise. So yeah, definitely try new games. There may be a learning curve but it's usually worth the effort.
