I need to skip one of these 3 games but can't decide which one?

Ouch. Tough choice tbh. I would say, if you want Fallout 4 the most, get that. Then, wait a couple of months until TR and Halo have been reduced in price and get them both :) All of these games will have a longevity attached to them due to multiplayer and/or sheer scale. Fallout 4 will easily last you a couple of months. So get that and whilst you're playing, the other 2 will reduce in price.
