Soloquendi

The one that got you hooked.  Where you would play it for hours and would think about it even when you weren't playing it. 

Dungeons and Dragons was the one for me back in '79.   The base was snowed in and we were stuck in the barracks, and somebody broke out the dice and books and 14 hours later 3/4 of our characters were dead, but we didn't care. 

What was yours? 

I like the idea of custom difficulty settings.  If death has no real penalty, then the game becomes boring to me.  Might as well play creative. 

A modest price increase to 10E for now, with stepped increases to 16E for each large increase in content.  When finished, to me it would be worth 20E easily.  The fact that it is moddable makes it worth more, in my opinion than a lot of games by big studios.
