What are you playing right now?

I'm fairly certain that the first Avernums had the walk-in secret doors, and the reboots are now using buttons and skill limits.

I admit, the naming of the series makes it somewhat confusing.

Anyway, not that it's an important issue.

Edit: Also a random factoid/blast from the past about the original Exile that it held the monster pictures as bitmap files in the folder. So you could actually go and mod the visuals to your heart's content.
