I bought an Xbox 360 and huge TV, instead of an engagement ring...
...then got pneumonia and was too weak to set it up, for SIX WEEKS!
(Bought a far nicer ring and proposed at my surprise 30th birthday meal, organised by my other half - so she finally forgave me)
I ordered an expensive rig (i5, 32Gb ram, 580 GTX SLI) for the release of Battlefield THREE, then received it 10 days before my son was born.
It soon became the world's most overqualified Peppa Pig dvd player.
I now have the above rig connected to my lounge TV, where I enjoy playing Diablo 3.
I want to upgrade it (mobo, CPU, ram, SSD & GPU) but hard to justify the £1500+ it'll cost, when my wife hasn't bought new clothes in forever....
...so I've been teaching my 5 year old son to play, in order to use him as a proxy ("Honestly darling - Elliott will be the one who benefits!")
I bought two Steam Links last week and have ordered a new TV for our bedroom, purely so I can play when *She's* asleep...
