OldOldGamer: I was 8 years old when Revs and Aviator come out.
I had my BBC Micro running those beautiful games (I was seeing them like that).
Then come the DOS. Lots of exquisite games, with manual copy protections:
Ok so you jumped directly from BBC to MS-DOS PC.
I know people had their share of problems with copy protections of many Commodore 64 games, like a game on tape recorded so badly that even the original copy would often fail to load (it was done in order to make any pirate copies useless), or all kinds of lenslock shit or whatever.
I was bitten right into arse by copy protection with the Amiga version of Gunship (Microsoft). It had several layers or copy protection and one of them, the modified boot sector on the game diskette, got overwritten and I couldn't play the original game anymore. Maybe that was the first time I really started hating these copy protection/DRM schemes.
PC/MS-DOS gaming had much less of that as far as I can tell. When I moved to PC gaming, I was quite surprised that quite often PC games didn't have much of, or any, copy protections or even "look up a word in the manual". It was quite different from e.g. Amiga.
As for modern DRM, I am kinda miffed now that I can't play my original copies of Plants vs Zombies or Peggle anymore, because the online DRM in them doesn't work anymore. The validation servers have apparently been closed down, I can't get past the part where the games try to validate the installation online. Fjuck DRM.
