1. Friends on xbox 2. Not everyone has money to spend on multiple consoles 3. Then we got to buy the games and dlc all over again and grind. Wouldn't be too fun. 4. Play alone for a while 5. Pay more money for PS plus (I hate Gold and plus regardless) 6. Have to split time between real life, xbox, and PS (or any other platform) 7. Just wasted money in general (not talking about the platforms, which are all respectively great).
