Soul for dcs, now we have nice sim but so,so sterile feel in it..
Better mission/campaing editor + better mission generator + better AI will help lot, and all old bugs get fixed finally i hope.
Graphics are not so important in sim , everything else is. (performance, AI, immersion, stability)
AND finally better spotting system, this is one of the best new things in 1.5/2.0 , no more so blind virtual pilots :)
