My Hero Ultra Rumble Review (DJMontague)
Game is incredibly fun. The people complaining about Gacha mechanics often think about the Genshin situation where a character than leaves the banner is not available anymore WHICH IS NOT THE CASE HERE. When the characters leave the banner they will be available with FREE Character Tickets. They have confirmed this on Twitter as well. Also they give you 5 Characters through the Free License system (battle pass but a permanent version). There is a regular battle pass of course thank you fortnite but still they are actively working and balancing a fun game. Some characters are stronger than others but in general most everyone is fun and you don't have to engage with Ranked if you don't want to. I personally have only purchased the $30 Pack and with playing the game I have all the characters except All Might (currently Account level 48 as of writing this) which you get with the License.
Costume gacha is mostly what gacha is going to end up being because you will naturally obtain the characters. Also currently a bunch of recolors and the skins aren't fantastic but you can also purchase some of them with Hero Souls (duplicate currency) and some with Gold
I give it a 8/10 it's not gonna be an e-sport anytime soon. But fun is what we play games for.
TLDR: Not as bad as people are making it out to be but most importantly ITS FUN.
