I’ve had a recent tendency of buying two copies of fighting games that I like; one for console and one for PC:
Guilty Gear (XX, Xrd and Strive)
Street Fighter 6
Granblue Fantasy Vs Rising
Tekken 8
Aside from those, I’ve bought Final Fantasy VII and VIII at least twice, but might get VIII a third time because my PC version is not the remastered one.
The Katamari games, UMvC3, SotC, and Dragons Crown prolly count too.
