Old-school RPG meats Stealth, I am loving this game. It's very tough at first, but once you understand its mechanics, it's really good.
If you want to try it, here is some advice that I really recommend you to read since the game doesn't really force feed its meachanics to you and it can be quite frustrating at first. I put the advice in spoiler tags for those who want to discover the pain for themselves. ^^ However, the advice does not actually contain any spoilers!
Have fun! :-)
