I'll have to admit, its embarrassing admitting why I hate Marathon. Nobody even asked. This may be insightful to
Men_in_Boxes
Don't judge me, lol:
1. It is a mean game
2. It is not made for me
3. It is designed to reduce their work
4. It is made at the expense of a PvE game I love
5. Nothing is replacing the PvE game, it will cease to be made
6. No extra things to do besides the anxiety
7. A mode game that repeats over and over with no goal, loot doesn't really matter, skill is randomized
8. A lack of friends and social skills, so no access to end game or compiler for me ever
9. A dislike of the Bungie business model
10. The community happily kicking me out and having fun without me
