Do I buy any games for XSX above what game pass offers? = probably not, my goal is to not to have to buy a single game for sxs in next 3 years.
Do I buy any games that are currently on game pass, or have been? = most likely not, that would be counter effective.
I got GPU because it is so cheap with "trick", 93€ for 36 months is what I paid in total. So if I would buy games that are in it, it would ruin the cheapness.
SXS is my fellow system to PS5, so there are still way too many games between the two systems, so even if few games are removed (that I play), there is others to play.
My goal for this gen is to buy less games, for PS4 I bought like 80-100 physical games (most on sales) + 10-20 digital from sales + all the ps+ games, and that is just too many to play
So, game pass is one part of my goal, it really helps with the "I want to get something new to try out" feeling, because to me game pass are basically free for the next 3 years.
Also, games that come to game pass + ps5 = I will probably play the xbox version as it is "free".
I just tell this because I dont have anything against to buying games you like and are in GP, but I personally try to limit the amount of games / year, and those games that I will buy are most likely not on GP/xbox.
In theory, if I would have only SXS + GPU, I would still probably buy less games overall vs traditional system without GP.
