I haven't finished this game yet, but after 6 hours of play I'm already convinced I got more than my money's worth.
So far I've found:
+ A great turn-based combat system. Simple in design, but quite deep in practice as you have to plan your moves, use the terrain and carefully manage your set of specialised characters. There is little randomness, so you can (and should) think several turns ahead in a chess-like fashion to win battles. (Though learning additional moves and levelling stats certainly helps a lot too.) So far I've only played on normal mode and found myself pleasantly challenged throughout.
+Sufficient freedom in character-customisation. There's not much item collection and hardly any inventory management, and the main hero is always a psion, but you can specialise him in various combat and non-combat roles and soon amass a large number of spells and abilities and magic orbs. You can only use up to 8 spells or abilities in any given battle, but you can select which ones before each fight which adds another layer of tactics.
+ An interesting and immersive setting with a decent story. The concept of a rag-tag band of rebels fighting an evil theocracy isn't that original, but it's well implemented and the world feels like a real place. The characters in your party aren't all equally well developed but they're all likeable and interesting to talk to. (Well, you may find some annoying, and some are meant to be annoying, but in an entertaining fashion.)
+ Partial voice-acting. You don't see that much in indie games, and the voice acting here is actually very good. The music is good too and fits the setting.
+/- Plenty of puzzles. Which eh, aren't really too interesting. Find hidden switches and decipher sorta-cryptic clues. In another game I might welcome the change from the hack-and-slash, but since combat here is anything but I'd much rather be facing a new tactical combat challenge.
+/- Decent graphics for an indie game. The top-down view is a bit odd, but the hand-drawn character portraits are nice and the in-game graphics certainly are never distracting.
+/- A mini-game that's suspiciously similar to Magic: the Gathering. I'm not overly fond of mini-games, but this one's much better than most.
- Slightly chunky interface and a lack of documentation on character-abilities. You mostly have to find out what your attacks do and how useful they are by trial and error, and that's only possible after you paid for them at the trainer. The manual gives descriptions but doesn't list prerequisites and at one point I found myself making a far-reaching character-design choice without even being aware of it. (An NPC asked a cryptic philosophical question that led to my character becoming an ice-mage.)
Still, there's a good wiki which can solve this particular issue.
Now there's the indie bundle deal where you can get this game for 1 euro there's really no reason not to try it if you like turn-based RPGs. In fact I feel a little ashamed for having paid so little for it. It's worth much more.
