It depends on what public you aim for.
In general and with regards to wargames, I tend to look for three things in PC versions...
-Real life OOB.
-Real life SOP for the era simulated.
Other things that I would add/like...
If no random respawns, then a mission editor. Some sort of LOS tool, as well as a elevation tool. A weather engine, a level of FOW, a data card for each unit with comparison capability. Just to name a few.
While at it, it´s about time we get some real nice looking maps and counters, along with a slik UI to go with it! Maps could be Google Earth type with contour lines for example. Just some ideas.
