MMORPG requirements

A lot of new MMORPGs that are coming out make it hard to keep up for some people in terms of their system performance. There are some MMORPGs out there that need proper gaming computers in order to run them. And as time passes the games require higher system requirements. Eventually this leads to people needing to buy new PCs as their old ones cant keep up. For example a computer from about 8 years ago would either not be able to run most MMORPGs or it would lag a lot on most of them making some of them even unplayable due to the extent of the lag.
