I know there is already a plugin to lunch games and emulators just wounding why we cant have a games section since we already have movies,pictures and music the only thing left in the htpc would be a games section.
These are just suggestions
My idea is something like this
-able to lunch emulators and pc games
-have a library mode from where it can list things like platform/console,number of players,genre etc
those are the basic futures then we could add much more to make awsome
-able to setup emulators within xbmc globally and per game basis.example some emulators need a option on for some games to work.So you dont have to have a mouse and keyboard to change things
-able to setup your controls globally per console and per game
-scrap info,screenshot,cover art,fan art,cheat codes,guides a site might not exist for this but i am sure we could figure out something.
-how about xbmc can detect a psx and other disc based games when you insert it into your cd/dvd drive and load up the correct emulator.
one thing that would be awesome but i think it might be just to hard an ability to have a menu pop up in game from where u can edit settings,save/load states,change controlls,see cheat codes and exit back to xbmc. even in game guide so if you get stuck you can read what to do while ingame

example of ingame menus:steam and xfire so its possible but i don't know how hard it would be to make something like that.
i found a plug in for a different media player app that has some of these futures its called mygames here is some screen shots of how it looks just for examples.
In game menu
i dot like the way it looks but i bet the skinners here could come up with something amazing.
this screenshot looks better
i don't write good so i hope you understand what i am trying to say
thanks
