I beat the first 3 Avernum games in a row back in 2017. They look like they were made in 1982 but they were actually (re)made in 2012.
The appeal of these games for me is if you go from:
pen and paper rpg > text adventure > graphical adventure > AAA software
each step the games gets prettier but the rpg becomes ‘less free’, Avernum strikes a great balance where it’s very free and looks…good enough.
A full review for it is coming once I finish this playthrough.
