So I've been considering getting Imperial Assault as I hear there is an AI app rumored to come out soon.
For those of you who play (have played) what is the deal with the expansions? What's the difference between the big box expansions and do they have to be played in order? Are the individual ally and villain packs just to expand the two player skirmish mode or do they actually add new characters to the campaign game that wouldn't be included otherwise?
The big box expansions include mini campaigns that are set in that setting, but the content of the expansion can be mixed with the core game to expand options all around, such as new heroes, new enemies, items, etc. Side missions are kinda one off none story missions that can be found throughout the products, as you play a campaign of IA, you do story missions, and then sometimes you have to do side missions, which are somewhat random generic missions you play out. So the core set, and each expansion has a campaign, which all have branching mission structure depending on who wins each mission, and mixed into these campaigns are side missions, which are randomly drawn from the side mission deck. Essentially lets your campaigns be unique each time as you have an ever growing collection of side missions, so even replaying the same campaign storyline, good chance you will play a bunch of different missions each time
The character packs, many of them are miniature upgrades that replace the tokens found in the various core/expansion sets. Each game set comes with only a few minis, and then tokens for other enemies/npcs that don't have minis. You can buy character packs to add the minis in. The packs include cards and content needed for playing skirmish mode, but they do also toss in some extra game content via new missions and other cards. So they are like mini expansions to the base game. Like Han Solo pack, comes with a side mission (the side missions typically involve the content of the character pack), and you also get access to a new reward card themed after Han Solo.
