Does Runescape count as a "video game"? I would say storyline is the most fun part of the game e.g. Runescape Lore - I would like to see how OSRS Guthix continues to live on as well as the return of Zaros. I'd consider "Free-To-Play" as a primary factor of a fun element and/or a fun element within itself as it allows testing grounds for people to appreciate the game before advancing in it further as I'm sure Runescape did for many of us.
Yes, of course it counts. Also, if you want to give examples, you don't have to talk about any specific games to provide examples (but it does help if you do).
online gaming with friends. to me that is one of the best things about gaming. Some games have become stale. But having fun with your friends can make almost any stale game fun! Games like call of duty use to be fun for me and friends. But now they seem to be way over the top with crazy things like jet packs and super abilities. The older COD games (which we play more then the newer ones) are more fun in my opinion. Playing search and destroy in the COD franchise can be intense. Many of the better players play the gametype as it takes more skill as you do not respawn. When your the last one left on your team sometimes your adrenaline gets pumping and it make the experience even more fun.
