Yeah, I have to agree with that, no other game has held me this long before.
I hosted a TFC server, then a DOD server, then a Red Faction server and admitedly, all were MUCH easier to admin, but nowhere near as much fun to play.
The way i look at it, if resistance' netcode is the same as 1.60 in it's current state, I will probably continue hosting a 1.46 server. I've already been through enough headaches dealing with the bugs we've had in the past, and am not really in the mood for more:-) On the other hand, if Resistance is at LEAST as stable and bugfree as 1.46, I'll gladly switch and not look back.
All these things aside though, I recognise that while OFP has been one of the most enjoyable games I've ever played, some of it is because it has so many original features, and an amazing sense of freedom. None of these things are really copyrightable, so if another, larger game company gets it right the first time, with a similar formula, better marketing, and better support for administrators, I'll probably close up shop and move on
Just my 2c though :-).
