I turned mine into a retro gaming console. Got it working, fired it up, and realized that the games of yesteryear are are terrible compared to what's out there now (IMHO) and it's been sitting since.
idk, it really depends. I haven't played the new Master of Orion but from what I heard it kind of sucked, which is a pity because they got Mark Hamill and John de Lancie and a bunch of other famous actors to do voice work for the game. They even scrapped the turn-based fleet battles. MoO2 is apparently still the best MoO2. From what I know something similar also happened with Civilization: Beyond Earth and Sid Meier's Alpha Centauri remains distinctly superior.
I don't have a dedicated GPU on my current system which is part of why I play old games. It's not really a high priority because I can do non-game stuff that requires one in the cloud and I have a huge backlog of games on GOG that I don't even have time to play anyway but when I get one I want to try Stellaris. It's a more recent 4X game in space and is very highly rated. There's even an expansion that lets you create a Borg-type race. *squeeeee* Until then, I guess I have good old
Seven of Nine Aki Zeta-5 to fall back on.
