Mass Effect 3 Message Board  

Someone posted a full list of war assets for ME3 at bioware forum if you want to take a look (Link). It should cover most if not all counted decisions from the trilogy. BEWARE, it contains heavy spoilers.

I already read it in the wiki, That ME1 takes effect in ME3. But seeing all that data is just going to spoil the game. Better to not know and work it out for your selfs.
