Underworlds was at $0.99 for a while, that was an awesome deal. I'd say get both, they're both great. Just a heads up, this'll probably get moved to the Discussion board.
underworlds is diablo-like rpg, whilst zenonia is more like old zeldas (haven't got it) underworlds will keep on growing but zenonia looks bigger and more polished
They are not even close in quality as Underworlds is shamed by Zenonia. While Underworlds has the Diablo-esque coat of paint, Zenonia has the meat, with TONS of interesting (and randomized) gear, multiple classes, developed skill trees, etc... Underworlds seemed good about a month ago and now it just looks like a joke.
Like others have said, they're slighty two different styles of gaming. But overall I'd go with Zenonia. Zenonia has more value and it's the better game because it has more content, depth and replayability. I have to say Pixel Mine did a good job with Underworld's graphics and sound, and considering it was exclusively made for the idevice, I think that should count for something. And Pixel Mine does promise to add more content in future updates so that's kind of cool. Basically, Zenonia was a port of a mobile phone game so the content was mostly there already and honestly as great of a game it is, I think it could've used a little more polish. Again, the game is really good and charming and its imperfections become an afterthought. I haven't really played Underworlds because it feels too counterintuitive and has too less depth for my taste, but after the promised updates I know it's going to be a gamer's favorite.
Both are fun, and U is worth getting (say 2.99 and below) because it is easy to pick up and play, and because the devs are adding content regularly. But Z has waaay more content, items, etc., and is an amazing bargain at 5.99. We iDevice users are so spoiled compared to DS, PSP, and so on. U is like a quick candy bar, and Z is like a full meal.
We'll have to wait 6 months for update 3.0 before Underworlds beats Zenonia overall. But Zenonia could need some pointers, cause even with Underworlds' cluttered and clumsy interface for menus, at least they are touch enabled.
oh. my. GOD. there is no question, Zenonia. Even if Zenonia was $20 and Underworlds was $0.99, Zenonia would be worth it more than Underworlds. Don't get me wrong, Underworlds is a great game (I've played through it on all difficulties. ) but if I had to pick one to get, I'd definitely get Zenonia. I have over 8 hours of gameplay (I have no life) put into it, and I'm still not finished with it. it is WELL worth the $5.99. Get it before Gamevil realizes how much more they can sell it for!!
I'd compare the lenght of both games. Underworlds - 2,3 hours. Zenonia - more than 25 hours choosing one story mode. And as the rest said - U is a candy bar, Z is a full meal. There were different items in U, but c'mmon! It's nothing when you see gear in Z.
