So I have finally rounded out my ranks with:

2x Core

1x everything that has come out so far

What else should I buy? I play mostly Imperial, but my family also really enjoys Rebel. I would like to buy another Interceptor, Bomber, and TIE. What should I get on the other side of the fence?

Well a 3rd core is a possibility, if you can find one for $20 or less, that's 2 more Ties and 1 X-Wing.

If another core isn't something you're interested in, I'd say rebel side, either 2 more X's or 3 more B's. People tend to undervalue the power of the 4 of a kind lists and how effective they can be.

this isn't really an answer to your question but regarding imperials you could wait till imperial aces comes out, although that would be 2 interceptors not one as for rebels if you mostly play imperials but some of the rest of your family likes rebels you could let them decide what they want for rebels

1-2 ties, firespray and perhaps an intercepter - but remember imperial aces (which has Push the Limit x2!!) is just hitting stores soon and it should be easy to find someone with some extra base-templetes/pilots for the name intercepter pilots.

for rebels imo you need a 3rd x-wing, y-wing and at least 2 B-Wings. Order of priority depends on what u like playing. Falcon is good too but imo not an urgent purchase on ur wish list.

thats they way id go, but thats me.

I think most people missed that you already have 1x everything.

So, you already have 3 X wings, and a Firespray, and a Falcon, I don't think a second FS/YT would be the best next purchase. I would probably agree with most that an Imp aces would be a good next purchase, netting you a total of 3 Int.

5 TIEs is a healthy number, but if you like flying them, you could probably do with 1-2 more... 6 named TIEs is a popular swarm list, and the 6+Howl is probably the best list in general right now (but rather boring).

Not a huge urgency to get a second TIE/x1. I would suggest maybe a second bomber on the imp side after you get imp aces. They typically don't do too well by themselves, but if you had 2 of them, and Vader in his Advanced, you have 3 TIEs for an alpha strike, not bad...

As for the rebel side, 3 X wings are pretty good, I don't really see any reason to get a 4th right away - you could sub in a Blue for any Rookie if truly needed. A second Y would open up build combos, but I don't see it as necessary at this point, double ion turret nerfs quite a bit of damage, and you could fly a similar list with a Y + HWK anyways. Depending on your play style, a second A wing could do well, two flankers actually start hurting, while one is just kinda annoying to the opponent. A second falcon is not necessary at the moment. Nor is a second HWK. But a second (or 3rd) B wing could be useful.

So, rebel buy order: B, A, B, Y (heh), X

Imp buy order: Imp Aces, Bomber, TIE, TIE (or another core if you plan on continuing to expand... cheaper to get core than the 2x TIE+ X Wing), Bomber

Overall: B, Imp Aces, A, Bomber, B, Y, {TIE, TIE, X}/core, Bomber

actually i missed that - u right Khyros - my ammended wish list would be...

1-2 ties, firespray and perhaps an intercepter - but remember imperial aces (which has Push the Limit x2!!) is just hitting stores soon and it should be easy to find someone with some extra base-templetes/pilots for the name intercepter pilots.

for rebels imo you need at least 2x B-Wings. Falcon is good too but imo not an urgent purchase on ur wish list. id actually lean towards a HWK-290 as well its git recon specialist which is a great upgrade on the bounty hunter

I will probably buy another B and X for the Rebels (giving me 2&4 respectively). I may just buy 2x Aces Packs instead of another Int, but another Bomber is a must.

EDIT: Will take Khyros' suggestion.
