If you are into RPGs' then you must play this game!
VP has a lot of secret items and dungeons so you'll probably have to play it a few times in order to finish it 100%, not to mention that some items, dungeons and characters can only be found in the hard difficulty level. It also has 3 different endings. If you trigger some special events you'll get to see all 3 of them, and there is also a time limit in order to watch the last ending.
The battle system is pretty good. It might be tough to master it at first but if you do, then the battles will become a lot easier.
Finally, in VP you obtain items and weapons by spending something called "materialize points" instead of money. The game has a set time limit so your actions are limited. In that set time you have to learn how to buy items and raise your level enough to beat the game.
Have fun!
