Kid shouldn't have been constantly taunting him.
Older guy shouldn't have lost his shit, and when he did, he sure as hell shouldn't have decided a visit was in order, as that's way past 'heat of the moment'.
However, no real damage done, apology accepted, and they're even playing each other again.
It's pretty much a step up from punching your mate in the leg for getting a kill streak. (As I'm thinking throttled is probably an extreme term, probably grabbed him by the neck for a couple of a seconds then came to his senses.)
As has been repeated tho, it's the Daily Mail, so 'vidya games are evil'. who'da thunk it?
