Price increases removed my 'impulse' buy factor.
I've bought a little more in recent years (after about a 4 year hiatus) only because in that time there was a solid quality increase.
That said, I'm back to painting what I have and reducing the pile of pewter and plastic on my hobby desk.
I also play less - but I stick with it cause we all already play (my friends and I) its hard to pick up a new system if no one else plays...
i've drifted towards 28mm historicals, and gotten back into RPG's to try and suck more of my attention away from GW.
