That's totally dependent on what/where you want to play.

Some servers do not allow the use of newer clients (i.e. p1999)


On servers that do allow newer clients, they may not offer the newer content..and conversely, older content may not be available to
newer ones because of the way the client is coded.

I can't tell you whether or not to buy the new RoF client, but the free one available now will likely be compatible in the near future.

When RoF first came out, the emu was modified to talk to that client. Unfortunately, Steam modified that download back in February and
the new binary information has yet to be added to the emu's code.

As for RoF, it mostly works, but there are things that are still incompatible due to the changes made in the client back in the HoT
expansion. There is work in progress to adapt these changes..no deployment date set.
