1.) I don't care what anyone says- this game is TOUGH.
As I mentioned, I've played mystery dungeon games since the start, so I have a pretty good handle on how difficult they usually are. That said, right off the back this installment makes you work for every last EXP point and (P) you earn, to such an extent that I've had to turn off my game and walk away for a few hours to regain my composure.
Firstly, the average enemies are just plain harsh. In the previous games it was easy to out-level the grunts on each floor and take them down with a register attack. Now, however, I get the feeling that these Pokemon have discovered steroids. No longer am I losing to the occasional boss battle, but instead am going down to red health on nearly every enemy I run across. Even with two partners attacking along side you, it can sometimes take two or three turns just to defeat a single enemy. If this is the case right off the bat, then I can only shudder at the thought of higher-level resistance later.
Additionally, enemies evolve after nearly every KO they achieve, meaning that if one of your team faints during combat, YOU will now have to deal with something roughly twice as powerful as it was before. The chances of this happening? Higher than you might think, given that the new A.I.s for team members encourages them to wander after every item in every room and away from the relative safety of the group.
Also, Monster Houses and Traps appear almost immidiately during gameplay. Yup, you got it- those unusually strong enemies I was talking about? You could randomly find yourself surrounded by ten of them, ready to evolve as soon as your weakest link fails.
Now, normally these conditions wouldn't be too bad. After all, usually after failing a dungeon you lose only a bit of your held items and money, then you can keep trying again and again as you level up right? Heh, WRONG. because in this game, every time you fail you lose ALL of your belongings. That's right, every item that you bring to assist your survival can be lost forever as soon as you bite the dust. This on its own is extremely annoying, especially since certain items aren't easy to come by.
