Simple answer, pick up a core box and see how you get on. First thing you need to establish is do you even like the game.Long answer is it depends. If you're going to play this a lot and regularly you'll want a lot of content to keep it fresh, if this is something you'll get to the table a couple of times a year then a core box will probably be enough.
I've also got Marvel United (went all in on all three campaigns still waiting on multiverse delivery). Much like MU the more DMD you have the more variety it will have, I'd say a DMD core box will give you more replay value then MU. I much prefer DMD to MU, but MU is a quick easy set up that works well for solo play.
As far as table space goes it depends again on you and the shape of your table. DMD works better on rectangular tables, MU works better on square tables
