We had those at school! My mate hate a Performa 600 and then about a year later I got a 630. Our dads would take turns ferrying them - and the enormous CRTs - to each others' houses at the weekend and we'd network them. Great memories indeed!
I think I've had the following over the years:
Se/30, IIsi, LCIII, LC475, some Radius Mac clone, then just boring 'modern' Macs. My current main work Mac is a 2010 Mac Pro that I've upgraded the heck out of. Fantastic machine. I could probably get inside it if I really wanted to.
Marathon! I loved that game. Fond memories of playing that on my LC475
