Nothing like the MMO games like WOW, FlyFF, or MMOFPS.
I was thinking if the developers can make a decent Elder Scroll MMORPG. The game would have PVP Arenas too(but max player is different from Story mode and they are in seperate servers unlike borderlands). The servers are room like kind of like borderlands. But max players for story 4-8(8 players would be nice, and please do make some bosses (Bosses can be random like multiplayer specific boss, can also be an expansion pack to download special multiplayer bosses with a whole new story line for them) require around 6 players to help defeat them, not neccesary 6 players, but really hard boss that needs at least 6 players to make it easier to defeat instead of just soloing everything defeat. PVP Arenas are seperate server with a whole a lot of different arenas you can choose to fight in(kind of like MMOFPS). Heck you can even have Game Modes add on as a downloadable content. Max players for PVP 16-32(FPS like)?
Then again that can help make some money. I do support the developers for making really good games.
Storyline + Co-op MMO
+ Downloadable PVP Arena (Seperate servers, so you can search the server for Story or PVP, PVP can have their own special content to make the game last longer)
+ Downloadable Expansions with new story.($30 for each expansions or something)
+ Downloadable Game modes(I expect this one to have like 2-3 games modes coming out at once, don't want something like 1 game mode every content that is just too cheap).
+ Trade-able market would be nice too(selling and trading armors and weapons). This could be in another server too as there are many people that could possibly be playing.
If not, should the next Elder Scroll have Co-op mode?
