I've been gaming for a long time. So I really dont' have a favorite game console. I have:
For each major console, I mostly the big flagship titles. For Sony: God of war, Metal Gear, Grand Theft Auto, street fighter 5
For xbox: Halo Master Chief Collection and halo 5, Gears of war
For Wii: Smash Brothers Brawl
PC, I don't really play that much anymore. I used to play a lot of FPS 10 years ago: Counter Strike Source, Half life 2, Far Cry, Rainbow 6 Vegas and Watchdogs.
But If I had to pick one console that I play the most on, honestly it will have to be XBOX 1. I put in A TON of hours of halo multiplayer. A close second place would be my ps4. Cause I also put in A TON of hours in MGS 5 Phantom pain.
