It would be cool that alongside the campaign, there would be scenarioes from frther down the line like the first battle for earth, the second battle for earth, battle for instillation 04 / 05 / 00, battle of reach and all that, with the only the sstuff, according to cannon, availiable, so on instillation o4, you only get marines, spartans, warthogs, pelicans, and scorpians. And earth you get everything in the UNSC arsenal.
and then there are flood bases all over the place that can be destroyed as a secondary objective and stuff only on the battles they were actully in like instillation 04/05/00 and the second battle for earth.
and they are all playable by both unsc and covies, to give players a covenant campaign-like experience.
so no scarabs, vampires or locust on instillation 04, but everything at 05 and you can only play brutes on the ark and earth 2.
Maybe we will unlock this sort of thing though, though timeline events.
But its these sort of things that we miss out on because we have no map and campaign editor! Bring them back! AOE II FTW!
