This is one of the best PS2 games I've ever played, and I wouldn't think I would like this type of game :D
Cons: Voice acting is a little gay(As with most JRPG games), but you get over it :D
Dark Cloud 2 is a game where you explore various randomly generated dungeons to help get materials and ideas how to build the towns in the game and fix the future! Now I wouldn't think I would still be into this game, with its B-rated voice acting (typical of anime) and very compound building town components (Need lots of different materials to build stuff), but I fell instantly in love with it (Not in the weird way :P) .
Anywho , you play as Max, a sheltered boy who really knows a lot about mechanics and such, who ends up being chased out of town by some f-ed up clown who wants to still this jewel (That his mother gave him) that Max has. Afterwards, he meets Monica, who says she is from the future(100 years). Turns out that Monica has the same type of jewel as Max, and it turns out that the jewels can actually transport back and forth to the future 100 years(You only have 2 time periods to deal with). Some villain is screwing up Max's time that effects Monica's and you have to figure it all out. You build your own towns to fix the future so that you can reach the antagonist of the game!! I don't want to reveal too much, so I suggest you play the game! You can get it pretty cheap now since it's a PS2 game!
