Sounds pretty simple to me. I don't see the problem?
You say Fallout 4 looked the best to you, plus it's a given that game will be able to occupy your time the longest (not counting investment in Halo MP). So that's your buy #1. Then you say Tomb Raider looked good, but Halo didn't really impress you that much, so Tomb Raider clearly is your buy #2. You get a great RPG, and a great Action/Adventure game. The former will keep you busy long enough till you can afford to go get Halo later, if you still want to.
