Playing Eschalon is a bit like slipping into a warm bath, at least for those of us who played computer RPGs obsessively in the late 80s. It's a tile-map, sprite-based, single-character RPG with randomly-rolled characters, multiple character types, and a bit of a story. Movement and combat is turn-based but if you hold the mouse button down, you move continuously in the direction pointed, so you can produce a quasi-action game, if you like.
The UI is very smooth; the only think that isn't immediately obvious is that you hold the shift key down and then click to bash open doors or chests. It's not a huge game -- three major towns, perhaps 20 hours of gameplay -- and not particularly innovative, in either story or gameplay (you begin as an amnesiac, forsooth). But it's pleasant, enjoyable, and good for a bout of nostalgia, at any event.
