Well, 'Super' hasn't always been bad in games.
Take Super Paper Mario. That wasn't a horrible title to many. It just was different with it's style of gameplay. Well, however this reasoning could be wrong because this as made before DLC.
Super in itself could also bring about a change to pokemon Mystery Dungeon, gameplay-wise. I have no ideas though. Or it could be F2P. Time will tell.
Now, what really gets to me is the Gold Backing on the logo. No other game in the PMD saga has used gold logos, or any metallic logo. It may either seem cheesy, or a quality of perfection that Pokemon wants to establish in this game.
The color change in "Mystery Dungeon" also gets to me. Reversing yellow to blue, contrasing colors. This contrast in the logo could have been decided because Pokemon wanted to make sure that this game was going to be different than the rest. However, as it's logo is similar to previous ones in font, maybe this game might also feel more familiar, probably more familiar than Gates to Infinity.
Now thinking optimistically, the quality of this game being F2P wouldn't be all that bad either. PMD games are already sectioned into days. One day in PSMD could be made equal to one real time day, and thus money would be required to skip to the next day. With that, A real Day/Night system could be instituted into the game, and that might be appealing. Also, waiting an amount of time between adventures and going from day to day at a slow pace could offer a more rich experience. Or if that sounds dumb, you're probably right. I'm reasoning with nostalgia here.
Overall, don't lose hope in this game yet!
