My impression is that G3 has been around longer so it has passed the stage of "bugs". It is a seasoned product with lots of add-ons. Here comes FS1 with the "kickbutt" attitute and there are lots of hype around it. It can be an excellent sim once it passes through the initial stage. I am suprised that the FS1 developers don't invest more time to render the planes especially the 3D fields to be more realistic. I think that give a year with at least 5 patches and add-ons, G3 will have a serious competition. DP
