Oh, no. Sometimes you can use swords.
More seriously, please don't take this as a personal attack on you, but that's the problem really. People think they're all the same, and don't realise that game B is far nastier than game A, etc.
Games are a new medium, and there's a huge amount of variation. As there is in films, another medium.
There are war games (CoD), monster-shooting games (Left 4 Dead, Doom), survival horror (Silent Hill), playing card games (Solitare- comes ready installed on many computers), farming games (yes, people play games where they plant vegetables, harvest them, and sell them- Harvest Moon, Viva Pinata), rhythm games (Rock Band, Guitar Hero), puzzle games (Minesweeper-one of those little games that comes ready installed on lots of computers, Bejewelled) puzzle games with storyline (Professor Layton), card-collecting games (like collecting playing cards, but virtual pixel ones), racing games, football and other sports simulation games (Fifa Season whatever), babysitting games, railway simulators. There's a huge range out there.
Just because one game or genre of game is acceptable/enjoyable to you doesn't mean any other would be. My husband, for example, detests survival horror, and I can't start sports simulators.
