This may sound stupid, but I'm telling ya - JUST TRY IT - you'll get sucked in faster then you can say "Glorious trip down memory lane!"
The big secret is actually no secret at all - it's YOU TUBE. Yup you heard me, youtube. I have found almost every single game I've ever looked for. I 'played' all the tex murphys from beginning to end, revisited ripley's believe it or not, played all the space quests - it's awesome! No configuration probs, no sound card hassles, no nothing! just search the game name, and bingo, you can prolly find movies of the game being played from beginning to end. You can even finally get to see all those multiple endings you said you were gunna check out - and never did LOL
