Reach is my favourite Halo.
Fallout 3 is hated now? Lol ok then add it to the list. I also love Fallout 4, and particularly the settlement system which some seem to despise.
Sure, it's no New Vegas, but they all have their quirks and gems.
Brink was also the shit but it totally flopped on release. A shame, because a lot of other TF2 copies like Overwatch and Apex took the lion's share a few years later but with much less depth to it all.
