I found Brawlhalla to be boring. It's, in my opinion, a bad smash bros clone with no recognizable characters to make it fun.
Keep in mind though I'm not a huge fan of smash bros in the first place so I'm probably biased.
You probably found it boring because at the first 30-40 hours you wont really know crap, at least not without searching. A lot of new players just spam signatures but lemme tell you this: The game gets much better when you learn combos and its much much more effective than spam xD anyways if you tried it for just 1-5 hours it'll be probably be seen as "boring"
Clicker Heroes isn't a game, it's a glorified screen saver.
