Makes you wonder how they managed to screw everything up with Boom. I'd also recommend Super Paper Mario. It's not a traditional RPG, but it's very charming and has a great story.
Is Boom really so bad ? The videos on youtube actually aren't bad at all.
Super Paper Mario is definetely a game that I will try as soon as I find it.
I've only played the demo of it, but I've seen tons of videos on it. I wouldn't say it's the worst Sonic game ever (that goes to 06) but it's really just another shitty TV tie-in game that got special attention because it's Sonic and everyone likes to make fun of Sonic (rightfully so).
