The older I get the more I realised that I love the anticipation of the item's arrival than the actual use of the item itself. Over the past 2 years I have bought over half a dozen retro consoles, each time I look forward to its arrival and setting it up but once it is set up, I hardly played them. Yet I still watch reviews and release of new models.
I also found I get the same kind of endorphin rush of looking forward to something seemingly trivial like a new set of keycaps to a new Macbook Air that I got the other day. Actually, the most exciting thing I have on pre-order right now is a Split Alice keyboard lol.
As for pre-ordering a console, I never have done. Normally just rock up on launch day or any day i am in town and bought in person, never tried very hard to get them.
