That game looks...meh, and that's mainly due to the gameplay; I don't know, it just looks a tad slow compared to the likes of Smash Ultimate and All-Star Brawl.
Not to mention some of the voices for characters I recognized (particularly Batman and Steven) sounded...off to me. It honestly reminds me of how off the voice-acting was for the 3DS version of Cartoon Network Punch-Time Explosion.
And again, it just feels weird to me that they're going with a Warner Bros Multiverse and not just limiting it to, say, cartoons or films or something.
I guess I'll keep an eye on this and see how it goes, but I'm concerned so far, especially with the free-to-play format.
Edit: Okay, I just went to the game's website and found out that (at least for now), the game doesn't appear to be coming to the Switch, so even if I WAS really interested in it, I wouldn't be able to play it, which would suck frankly.
