Alright then. Here are the top three aspects of a game that make me love a game.

#1: Immersion. If I can get emotionally invested in a game and care for the characters, the world, the story, even the antagonist, it has succeeded. These kinds of games utilise the video game as a way to tell a story, much like a book or a movie, but they also use the advantages of a game to provide you with the feeling that you are part of the world and not just watching events pass. If a game has this feature, no others truly matter - sure, they are nice bonuses to have, but I already have more than I could ask for.

#2: Challenge and Strategic Flexibility. I like it when I am given bricks which I can build up in different ways to reach my goal. When it's a challenging task to find the correct order, even better. The flexibility is what prevents it from being a simple puzzle game and makes it something more rewarding. YOU found YOUR way, not THE way. Of course, challenge is mainly only welcome when you're ready for it, but when you are, it can be pretty awesome.

#3: Multiplayer. Singleplayer games are awesome in their own right (and I think #1, Immersion, works better in Singleplayer), but multiplayer take simple enjoyment to a whole new level. It is a lot of fun to face challenges with a friend by your side, and from time to time, it's fun to do a competitive match to prove your skill. Multiplayer is IMO the most fun if the people you're playing with are sitting right next to you, not in front of their computers a hundred miles away, but there's some merit to both of them. I can't really describe it well other than saying when you play with others, you'll just have a great time.
