I still play SH3 now thanks to Jęsens work and the GWX and others' work....even after I bought SH4. Even after Ops Monsoon and all the other excellent SH4 mods. But this hasn't stopped me playing SH3. I am not saying one game is better than the other (don't even want to start that discussion up). I play both games regularly. They have both their own merits and faults.
We havn't even seen SH5 yet.....just an entertaining trailer. Who says we won't be playing SH3 + 4 long after SH5 is out and modded?
Look what the Grey Wolves and other modders did for SH3. And what Lurker + many others did for SH4. THOSE GAMES DO NOT DIE just because a new one comes out.
Really looking forward to SH5, but still enjoying 3 + 4.
Would love to see a GWX4....whenever. You have also got lives to lead outside the game, as Jimbuna rightly points out. All I can say is I've enjoyed and appreciated your work. Good luck with whatever you all decide.
