Is it worth to play?

I recommend trying out Paladins! It's similar to overwatch and free to play. Could give you an idea of how the game is before you purchase it.

Every game is different for everyone. Overwatch feels like a very casual game to me and the character's differences make it feel like a customized TF2.

If you'd like a faster paced CS:GO with some superheroes in place of the T's and CT's, then the game might be what you'd want.
Just make sure to do lots of research first and watch others play the game before you invest money into it. It may be pretty old, but the price is still way up there.

I was also wondering if its worth the money of if I'd be better puting my money into something like Battlefield 1??

Battle Royale games are on top these days, I'd go with PUBG and Fortnite, on the other hand GTA:O isn't that bad but the last DLC was trash, so.
