So the original post seems to be changing a bit, don't know who or why that is and doesn't bother me either tbh.
But there is a question in there now about games that end.
There are LOADS of RTS MMO's that have a definite end to the server. I have played a couple - Grepolis and C&C Tiberium alliances. Both good games btw.
The games have a define scenario for how you "win" the server. In Grepolis it's your league/team completing production of a mega structure first and in C&C it's being fist to reach the centre of the map and kill a pretty difficult NPC base.
If you never played one it might seem strange but it's one way to try and keep games balanced.
If you join Stormfall now you are 7 years of growth behind some of the long term players. That puts you at a significant disadvantage (and that is without even going into the contentious area of money). For two players of equal skill the one that starts 7 years late will never be competitive with the one that started at the beginning.
Some games address this by running many servers of the same game which have a finite end. There is a new server starting pretty much all the time. So all the players start on a level playing field.
If you enjoy the game, the intention is you would start on a new server when you current server reaches it's natural conclusion. They don't turn the servers off immediately, just when people lose interest. For instance in C&C you get a medal for your server participation and you still get a medal if you league is 2nd, 3rd, 4th etc to finish the end game. The medal are associated with your accounts and some people build up these medals on many many different servers.
Obviously there is a major downside to these games. You get the balance of everyone starting within the same month but everything you do will eventually be lost and if you want to keep playing you need to start a new server from scratch. Clearly this works cause people play these games.
Not saying either way of structuring a game is better. I think largely they just appeal to different types of people who value different elements of gameplay differently. But since you asked the question thought I would share that there are very much definitely games which have a specific end.
