I'd like to put forward a small suggestion if you're missing HL2RP and really want to do some roleplay on your characters.
Steam roleplay.
For all I know some of you might be doing this already, but if you're not, steam is always there for you guys to roleplay, and as long as you're not doing like promotions/shooting/pking/killing type stuff (aka, passive roleplay only) then the roleplay that happens in steam can easily carry over to the server, assuming it's not massively going to change things or whatever, you know what I mean...
So yeah, if you're missing your buddies in GRID, or missing your usual roommates in the UCH or usual killing-mates (haha joke) in P3, why not get together in a steam group chat and roleplay there? Might not be as visual but this does tend to help your roleplaying skills, relying on purely typing rather than typing + visual/3d stuff.
