Still a long way to go before this becomes law. A very good chance it won't, especially since it seems the issue has fallen out of the media spotlight at least some.
That being said, presumably any T-rated game offering loot boxes would seem to fall under the legislation's purview. Just off the top of my head, that would include Overwatch, Fortnite, Apex, Destiny...a lot of big titles.
Last time I can remember something like this happening is playing through Saints Row 2 on the PS3...game kept hard-locking whenever I attempted a required story mission. I eventually gave up on the save, still have not gone back to finish the game.
I voted for ME3. The ending is fine. The gameplay will feel a lot like ME2. Regardless of how you feel about the ending, there's some great story beats along the way that the series has been building to since game 1. ME2 is one of my "games of the generation" and I would rank ME3 quite a bit lower, but it's still a satisfying end to the trilogy IMO that's worth seeing if you've invested in the first couple of games.
Edit: Definitely grab the Citadel DLC, because it's one of the best things in Mass Effect 1-3, and I thought the Leviathan DLC was worth seeing as well.
