I'm not sure if someone already made something similar to this thread but what shooter series do you guys prefer? Spoiler I think it will be COD or TF
Halo, because it has one of the best campaigns and its skill based MP is the best, with skill based ranks, map control, and weapons control. Also, because Halo expands way beyond FPS, there's an RTS game, Halo Wars, many books and comics, live action series and an anime called Halo Legends.
Tf2/CS:Go. The games are amazingly balanced and competitive. Not to mention you can have a lot of fun in them(Especially on TF2). If not those then I would say FarCry 4. The campain is really nice, I love the survival options, and the multiplayer is actually really fun. It just needs more players and less lobby wait time.
I forgot to mention that in Halo, the custom games, especially in Halo 3 and Halo Reach, are the best. The player made maps and game mode make the best mini games. I loved goofing off with friends on split screen back in the days. Mini games like Fat Kid, Splatter Monkey, Toy Factory, Crash Up Derby and Rotunda were awesome.
Counter Strike and Team Fortress EDIT: Add GTA V for PS4 since you can shoot people while in first person mode
Because all you play is COD, there's a lot more unique FPS games out there. Star Wars Battlefront is an awesome one.
You noob, the new one isn't ANYTHING like the first two. This one is being developed by Dice and EA, the worst possible companies to make the game. SWBF 1 and 2 were legendary.
Grand Theft Auto 5 is my favorite one but it is probably because it is my all time favorite game I have it for all consoles even PC. :)
