In the collection is the 3 games as they are also for sale individually at the moment. The first part with two extensions and the second part with the "Cerberus Network" as in the Digital Deluxe Edition and the 3rd part in the Standard Edition.
Who already has one of the 3 games for the the pack so not worth it, because the savings for individual purchase is minimal. But if all 3 games will, which should access.
The DLCs: The missing story DLC for ME2 together cost 2800 BW points, ie 28 EUR. Then there concerning appearance, armor and weapon packs for 800 points, which is 8 EUR. The 2 missing story DLC for ME3 together cost 1600 BW points, ie 16 EUR. And 2 weapons packs for 3.20 EUR. (Yes, 100 points = 1 EUR, the prices were increased)
The games are all great. Who wants to know more accurate 3 games can read the reviews of the individual securities. I find that the trilogy's worth if you still have none of the games. Too bad that you again have to spend 44 EUR for DLC if you want to play everything (the weapons pack I do not count as a game content) but when the trilogy would have cost with all the DLCs then 99 EUR have people just bitched.
