it's too big and too complicated. I hope you got answer from L. because this is at least month work. In my opinion, you (or your developer) can:
- develop everything (game plugin, review plugin etc) special for you // this was my first idea because everything looked too custom
- use book/chapter/page system inbuild in e107
Problem: missing frontent posting, missing author's system (I call it - it's one man show - user get admin access and then have access to everything, to other user's pages)
- use old content plugin
Problem: it's old. I use it on my own risk.
user can post only with Submit news.
So you can use News module with categories:
News (actual news)
Then you need "connect" game with news (4x) and special solution for display on game profile page (better idea: "connect" news with game, it can be done with e_admin).
On other side - all those news will be (can be) displayed under News section like separate articles. Correct?
