To be fair, the first one was released the year PS4 hit 100 million units + ~ 40 million Xbox One + PC.
The second Jedi game was released when there were like ~20 million PS5 + ~10 million Xbox Series X/S + PC, so with that in mind it's kinda surprising it made it to the top 10.
PC only for JK and PC/Xbox only for Kotor will do that. Install base of the first Xbox was like 25 million tops. And the ports & rereleases over the years for Kotor probably haven’t moved the needle much. If they’re even all tracked.
