GOG.com is undoubtedly the best place to go for fully compatible old games on the PC. It is, however, the only place to get them all 100% DRM free and for that they should be applauded. GOG.com are unable to guarantee that they will be allowed to keep selling these games in their store as their current agreement with Interplay will expire and the rights will then belong to Bethesda/Zenimax.
If you don't know about Fallout 1, 2 and tactics they are classic, old school RPG's with an isometric view set in a post apocalyptic world and they are very worth your time (Tactics not so much but hey, its free!) and at this price, definitely worth your money!
Get in quick as this deal will expire soon and don't forget to check out the 600+ games for sale. They are discounted up to 50% with bundle deals up to 80%!
