With Outcast, ss far as I could tell, from the start of the game (I've only been through one gate), it seems to be similar to Dragonriders of Pern. (Or, for those who know Outcast, and not Dragonriders, Dragonriders is quite remeniscent of Outcast!
, especially in the 'easy combat' and task-oriented puzzles area)
Outcast is interesting from a technical perspective because of the reasonably organic ground textures... not your normal polygon map!
I'd certainly agree that it is worth about $10 - possibly a bit more. However, I have yet to complete it, as I have a number of other games to play at the moment...
