I just don't feel like these three people are the same:
1. Plays candy crush all day (Facebook game).
2. Plays Call of Duty/Fifa for 2-5 hours a week.
3. Plays Call of Duty/Fifa for 20+ hours a week.
4. Plays LoL/Dota/[insert MOBA here/[insert MMO here] for ___ hours a week.
5. Buys a game every few months, plays it over the course of a couple months then gets a new one.
6. Plays that one game that they love to death, and rarely plays anything else. Waits for the sequel, then moves on to that. (e.g. Pokemon, Dark Souls, etc.)
7. Plays obscure indie/PC games mostly, occasionally plays games they deem 'worthy' that are more mainstream.
8. Plays old-school stuff, doesn't care for new stuff. Still plays SNES.
9. Plays a variety of games of all genres, likes to be up to date in current gaming trends/discussions.
>9Also, I feel that the only difference between 5 and 9 is budget.
