Bastion has one main trick, but it's an excellent one - throughout, your actions are narrated by a character called the Strange, a richly-voiced Southern gent. What's so marevllous about this is not just the sheer amount of voicework or the extent to which it really does track your actions, but how the nrration device is used to build a fascinating world. The Stranger is terse, always hinting at more than he explicitly states - not only is this effective for the world-building, but this sense of evasiveness becomes increasingly key to the game's plot.

Gameplay wise it's roughly an ARPG Diablo-like, although there's not much focus on gaining levels and rather more on customising your wapons to suit your playstyle. There's somethign liek a dozen of them, you carry two at at time (keyed to left or right mouse) and they're all different and interesting and satisfying to use, although you'll surely develop favourites.

Worth playing to the end.

I have played this game to 100% completion four times.

It's great.

If you're into roguelikes (Nethack, Zangband and their kin) in a big way, then you'll be disappointed by Dredmor's comparative lack of depth, challenge and variety.

If you' like the idea of roguelikes but have been put off by ASCII "graphics", bewildering controls and impossible difficulty, then buy this immediately.

That's about it really. It's also genuinely funny.
