Well the FTL is in minimalistic graphics, but it's not an that old game. FTL was originally released in 2012 so it's already 6 years ago, a major update called FTL: Advanced Edition was released 2014 so this is still in the era of modern computer games.
If you ever find FTL on a good discount, I recommend you to grab it and test it out :)
I will see if i can find it for cheap, i will go for the Advanced Edition if i do tho :P
