Rollercoaster Tycoon Classic seems pretty good so far. I don't think there's any free-roam mode where you can just build and run a park, but there are scenarios where you have a few goals to reach. Maybe you can just keep on playing on your own pace in here. I don't know which elements from RCT2 are in there as well, as I only ever played the original on PC.
Controls seems alright. You can zoom in and out by pinching, but it isn't a continuous fluid zoom, rather it zooms on different levels. When you need to rotate the camera you have to press the arrows at the top right corner, where I think I would have preferred to rotate with two fingers. It also seems like you have to press the build button for each square block on the ground every time you want to build a path or queue, instead of letting you choose your path by just drawing it with your finger.
Besides that, it have the classic atmosphere, feeling and music as well, so this might end up as my GOTY, if the controls doesn't turn out to be too cumbersome. I'm pretty positive on this one so far.
[edit] The horror game Forgotten Memories is on sale too. I just bought it. Gonna try it out tonight.
