So. Anyway. I didn't buy a PS1 for GT1/GT2, but I have bought four copies of GT1 and three of GT2
GT1s PAL - £24
GT1 NTSC-J - £8
GT1 NTSC-UC - £7
GT2 PAL - £30
GT2 NTSC-J - £5
GT2 NTSC-UC - £9
PS1 cost - £83
And, while technically I didn't buy a PS2 just for GT3/4, I did buy 3 others just for GT4
PS2s PAL - £100
PS2 NTSC-J - £150
Oh and three copies of GT Concept (2001 Tokyo, two copies of 2002 Tokyo-Geneva), three of GT3 (all regions), two of GT4P (PAL, NTSC-J) and 5 of GT4 (3 PAL, NTSC-J, NTSC-UC)
GT3/4/C/P - £180
PS2 total - £430
Neither of my PS3s are just for GT5/P and nor is my HD screen - which mainly sees MW2 actions - but I do have three copies of it (NTSC-J, PAL, SpecIII NTSC-J)
GT5P - £60
PS3 total - £60 (so far)
The PSP wasn't bought just for GT either - though I know some people did buy one for just GT - but I do have two copies of that also.
GTPSP - £60
PSP total - £60
And then of course I have collected the odd special edition here and there. Like GT2000, GT3 Replay Theater, GT Concept 2001 Tokyo press pack, two GT4 press edition (#555 and #1662), GT PSP Collector's Edition (included above) GT5P Spec III (included above), GT5P press pack and Attack Gran Turismo special DVD.
Special editions - £170
In terms of equipment, only the three PS2s already included were GT-specific. None of the PS2/3 peripherals really count as GT-specific - speakers, screen, headsets, PS3Eye - except the Logitech DFP (£50) and G25 (£150). And of course my driving rig which cost next to sod all.
Equipment total - £200
And then there's LANs. I've attended three in Wycombe, one in Sheffield (for which I built a venue), three in Newark, one in Banbury, one in Holland and four locally (for which I also built a venue).
LAN total - £1,500
So, only including consoles bought specifically for GT (the NTSC-J PS2) and GT LANs (two of the PAL PS2s), and without the cost of any of the hardware bought just to play the consoles on...
PS1 total - £83
PS2 total - £430
PS3 total - £60
PSP total - £60
Collection total - £170
Equipment total - £200
LAN total - £1,500
Grand total - £2,500 (forget the £3, it's only ballpark anyway)
