I will simply start by making it clear, whether the ending is good, bad or a talking bloody fish is of no interest to me – I am still working on ME 2 so at the moment the ending means bugger all to me.
However I have put in some time with Mass Effect 3 and feel that is enough time to get an opinion about the game itself.
Now game-play wise you can not fault this ME3 at all, it takes what has made the series good and continued along those lines. Combat is solid, Story (so far) is engaging and well written – all in all very worth playing if you have enjoyed any of the series so far.
Oh and the ending is getting fixed with DLC so stop talking about it already!
