Dark Spire is a new 'old school' dungeon crawl for the DS, similar to Etrian Odyssey. You form a party of 4 adventurers and venture into a Tower to recover the crown jewels...or something. There are 4 starting races: Human, Elf, Dwarf and Halfling and 4 starting classes: Warrior, Mage, Priest, Thief, with unlockables available eventually. You can also pick your alignment (zomg nerdgasm) and ROLL your stats; did I mention the game seems to draw heavily from D&D? When killing monsters, you earn Exp, but do not level up automatically; instead you spend your EP to buy class levels (in any class you qualify for), stats, skills, etc. This gives a decent variety of customization that most modern games are lacking in. Want a tank-mage? Go for it!
By the way, this game is HARD. Much harder than EO2, about on par or worse than EO1. There are numerous random encounters on the first level of the dungeon that can easily result in a wipe (Scoundrels, Killer Bats, I'm looking at you).
