If you have been playing computer games for a long time and have fond memories of games like for example:
Wing Commander: Privateer
Master of Orion
Heroes of Might and Magic 3
Disciples II Gold
Might and Magic series (World of Xeen and more)
Baldur’s gate 1+2
Fallout 1+2 and Fallout Tactics
Neverwinter Nights Platinum
And many many more!
GOG.com has the answer for you. They have struck deals with the respective owners of the intellectual property rights for all of these old games and can now sell them fully functionally and legal.
And many more you can find them at GOG.com (Good Old Games) where you can purchase the games from USD 5. All the games work on current PC’s as for example Win 7 etc. The games run in DOSbox that is a DOS emulator. You don’t have to bother with the tecnical stuff at all though as GOG has provided an installer for every game that works perfectly. So all the games are a one click installation and you can play.
You also get the manual and walkthroughs/cluebooks where relevant. As an example with Might and Magic 4 & 5 also known as World of Xeen I got a cluebook and maps for the whole games that really helps make the experience enjoyable, as the automapping in the game isn’t that great and some of the puzzles can be really hard.
I can really recommend that you visit GOG.com and see if you missed any of the classic games of your time or want to revisit a game or two. You can’t beat the price and quality that is encompassed in all of these old all time classics!
