You don't get the appeal of playing on a console?
Just a few reasons that could apply:
1. Your friends play console.
2. Console exclusives. PC has a way bigger library of games, but if the one you must play is only for console then what else can you do? Games like The last of us, Uncharted series, God of War are must play games (imho) and can't be played on PC
3. Consoles are slightly cheaper, but as soon as you want to play online or buy some games that pretty much goes away. Still, its a consideration for some people
4. Its what they have always done. Lots of people only play consoles cause they have never had a PC and they don’t like change.
5. Believe it or not some people prefer playing FPS games on consoles. I agree with you, PC is way better for FPS games.
6. Some games, like Sport and Race games, play better on console then on PC.
Why not enjoy both? Stop hating on people who like playing on consoles. Let them have fun.
