I really like Legend of Grimtock, even though I kind of got stuck on a puzzle and I feel like I need to give the game some time before trying yet again to make some progress.
While not playing old school role-playing experience from Almost Human, I have thought about how the series, which apparently recouped its development cost one day after the official launch date, could expand and diversify.
The most obvious target would be an extension of the current adventure, taking the characters the player created for Legend of Grimrock and giving them new areas to explore, somewhere around the mountain, new enemies to battle and new puzzles to solve.
