Well Im not moaning, or not much anyway
I put RS at the moment very much in the same position as MSTS when it first came out. Then, much like others, msts did nothing for me after waiting ages for its arrival, and after playing it for a while I put it away until EB's LBE came out and inspired me to find out how to write activities.
RS will be the same. Ive installed it and have been pretty much uninspired by it. It isnt at all user friendly and its does have some bugs, as well as a fair bit missing from the wish list but not as much for me as others. At the moment as a Sim i think its little better than MSTS as it was 6 years ago, and nowhere near as good as it is now. Certainly I see nothing in it at all to make me go WOW and want to start creating scenarios. But who is to say what it will be like 6 years down the road.
So i'll take another look at it after the development tools come out to see if that changes my view at all, otherwise I'll look at it again next year sometime when some of the bugs have been fixed and some of the wish list have been met. Until then, for me, it remains a rather poor 4/10 score, but with the hope it may get better.
