I think it's kind of odd that there's all these TF clones now. Maybe I'm late to the game, but it seems like the last couple years there have been several popping up. Overwatch is obviously the big topic now. Blizz did a great job getting the word out and hyping it up and I'm excited for it regardless of the price because it just looks awesome. There are already eSports teams dedicated to it, so it's going to be competitive, which adds a whole other playing field.
I got into the closed beta but completely forgot to download it lol. I'm glad it's open now because I've been wanting to play it really bad.
There's also Battleborn, which I've seen videos about at Gamestop, but I haven't really heard anyone talking about that much.
There's also Paragon by Epic Games, but I guess that could be more of a Smite clone. Some of the characters look eerily like ones from Overwatch though.
There's also Dirty Bomb, which has been out for a while now and is *free* on Steam, but I really haven't ever seen any ads for it. There's gameplay on YouTube but the only reason I knew about it is because it was a suggested video.
