My gaming started with the Atari VCS, moving to the VIC-20, then the C64.
I became a staunch Amigan: an Amiga 1000 in November '86, going through to a second-hand A500 in about 88/89, and then an A4000/030. Many games on the Amiga were also coded for the PC, but the Amiga always seemed to have an edge, despite the cost differential between the systems. Graphically and sonically, the Amiga seemed streets ahead.
A friend of a friend got a PC (486) around '94, and then I saw Doom. Hmm, this coupled with the start of Commodore's demise made me consider the PC as a viable game system; I already knew it had better DTP and other applications than the Amiga would ever get, so I umm-ed and ahh-ed a bit. Then at a computer fair one Sunday, I saw Little Big Adventure running on a PC, and knew I had to have it! I bought some PC mag coverdisks (which you could do then) with the odd full-price program on, plus games demos, and set about looking for a decent PC.
In mid-'95 I ended up with a machine from Evesham Micros (ex-Amiga and ST suppliers themselves), consisting of a Pentium 75, 8MB RAM, a quad-speed CDROM, a Soundblaster 16 sound card (ISA, of course), DOS 6.22 and Windows 3.11.
Then came a flurry of games: Doom, Doom 2, Rise of The Triad, LBA, Dark Forces, Bioforge, Alone in the Dark, Ecstatica, etc.
Since those early, heady days, my gaming has rather tailed off as free time has tailed off. The PC is still my prime game system (my most recent console is the GC), but I tend to play very little currently, and even then it's Sudoku and AisleRiot (solitaire) on Linux Mint, and through Virtual Box, Age of Empires on a virtual Windows 2000 PC.
I've reassessed some of those early PC games that I'd previously discounted because they were 'also on the Amiga'; while the Amiga version of game 'x' might have sounded better, say, it was more difficult to play because you couldn't install it to hard drive, and came on 3 floppies.
