I played RO1 from week 1, through 5 years including the various mods right up until the beta for RO2 was released. Yes, I do know what I'm talking about. I don't see that much of a difference when you consider that the engine is different.
In fact just to be sure the past month or so hasn't warped my memory I just loaded up RO1 to compare. The shooting mechanics are not that different. The guns come quick up to iron sights and centered in both games equally.
The only differences would be the difference in the engine and I would say as a long time shooter of many of the real life versions of the in game guns that the new RO2 is the more realistic of the two. Where would you say there should be more recoil? Which gun, and why? They seem pretty close on to the real thing to me. THe rifles for sure, the MP40 for sure, the SVT for sure. I have not fired a PPSH, but firing my Tokarev pistol (same round) fast, I can see the PPSH may have more recoil but hard to tell not firing it; the 7.62 x 25 round is a hot one, much more of a bang than the smaller 9mm round the Germans used. THe MKB I've also not fired, but have fired a .308 at full auto and I can tell you it is not that hard to keep that big heavy M14 on target for the most part, the recoil in game pretty close to the MKB; it would be just as easy to keep the big heavy MKB firing a similar round on target.
Give a bit of time and anyone who is a regular will be an "expert" at being able to shoot all the guns in game regardless of any dumbing down or gearing up that some people or don't see. This is as it should be, the mechanics just add or take away time to get to this....and as I said, the way it was with RO1, when the map makers get to it, there will be a huge variety of maps that suit many more play styles. There will be less complaining then, and I imagine a lot less MKB's as the map makers and server admins have more say over realistic loadouts.
