A concern comes to me: What happens if SE5 releases around the same time as Dom3? Will it overshadow it a reduce the population of acceptors that might otherwise have turned to Dom3 for thier strat needs?
That is a possibility but the dedicated strategy types will get both I think. Provided each one is deemed a quality addition to their respective series.
It might actually bring more attention to Dom3 as those previously unaware of Dominions glance about the forum and website.
I found SE from MOO2 and then found Dom2 from SE
