I like playing modern warfare. My pet peeve is twofold
1st, online is completely unplayable because of script kiddies having to cheat because they think their k-d ratios are more important than letting people have fun that want to play it they way it’s designed.
2nd on the campaigns the enemy players can shoot you through walls and kill you, but if you see them and try to shoot them through the walls, the walls become bulletproof.
Another game I like is GTAV online. They should get rid of the ability to buy virtual money packs. Not everyone can afford to pay $100 for $10 million virtual dollars to buy the shit that gives them the essence of i destruct ability. Oppressors come to mind on this. You can steal peoples cars left and right but if you steal an oppressor they can reclaim it while you are in mid flight killing you.

That first part is why I stopped playing the Resistance series. I really didn't care for the Auger being able to shoot through walls.
