Play them back to back! It offers a really nice juxtaposition. I did a whole half life playthrough with all the mainline games + VR and HL + BM :)

Black mesa is so insanely good.

Judging by all the shark card crap they jammed into the last GTA, I fully expect them to shovel a bunch of crap in to make more money: $70 base games, deluxe editions, DLC, micro transactions, social club integration, required internet connections, all of it.

I miss the old GTAs before they got greedy.
