Ack, Wild Arms 3 doesn't let you continue after you beat the game? That's one thing I loved about the first WA is continuing it after beating the main story.
I'm currently playing Shin Megami Tensei II. I'm playing a translated ROM on my PSP. Seems the only time I get to play games is on the bus. I really like this one even tho it can be a bit frustrating not knowing what the spells are or whether the equipment is better or worse than what you already have. There's some really clunky interface issues with the game, but I've played enough old school games to be able to deal with it. The MegaTen series is an odd one for me. I seem to like certain ones but not others. For instance, I couldn't get into the first SMT game, but I like this one a lot better. Nocturne, likewise, seemed fun but I kinda just put it aside. I'm not that into the Persona series, but I like what I've played of the Devil Summoner games (the U.S. ones, not the ones on the Saturn, which I haven't played yet). I also mostly enjoyed Devil Survivor, but the ending is a bit of a slog.
So right now I'm at the point where you come back from visiting their utopia and find that the Center is overrun with demons. I kinda already don't like the Mesians and want them to go to H-E-double-hockey-sticks, so I'm not sure how I feel about this latest development. (They breed demons for... food? The kill people in cold blood for worshipping a different deity? They apparently brainwash workers to keep them complacent?) I'm suspecting there's going to be some sort of moral question somewhere where you have to pick (or get forced into) sides, but so far I've just gone along with everything, and I've been using the Mesia facilities exclusively since they're convenient. This is one thing I don't really like. I always get the feeling I'm screwing things up when playing these types of games and that i'll have worked myself into a corner only to find I'm the second coming of Hitler by the end of it. Devil Survivor was the big one for this. I actually didn't like ANY of the choices and would have been happy telling the angels AND the demons to go to H-E-you-know-the-rest. I sure as shit wasn't going to sneak out tho, thanks Yoohoo. I didn't even get the option to fight against the angels, I guess b/c I was too much of a goody two shoes. I was also disappointed in the party I ended up stuck with by being too nice.
