If I own all the expansions of the 3rd edition. How hard would it be to convert my game over to the 4th edition? Are there components that I would be missing?

The tech decks are completely different

The race sheets have been redone and contain more critical info and some info is different

non home system planets have additional icons

the action, objective, and agenda cards are all different

strategy cards are changed

Basically, the dice are the same, and you can make do with the old plastic pieces. Everything else has at least some alterations.

Still, I think you could rather easily import many of the features:

The Mecatol Token and 1VP for taking it (There is already an Imperial 2, that is similar to 4th).

You could, if you wanted to, assign colored prerequisites to techs. It's rather easy to just count out the needed techs for it. However, TI3 seems to have a lot more tech-planets that may screw with this.

It'd be a little harder, but the trade part could also be ported - just add together the trade agreements for your total Commodity.

You could definitely postpone the political phase to work like TI4. I believe that would be quite seamless.

Allow players to trade Prommisory notes.

So quite a few streamline changes, and definitely not fixed with a few hot patches (and the 2nd expansion in my case) to 3rd ed.
We always played with the Distant Suns option...though playing without it makes for a tactically safer start, that's for sure. Happy to play without it.
All in all, I'm pretty d**n excited for this new 'all included' 4th ed, though it's $250 dollarydoos through my FLG here in Australia.
