The above is an example of what I mean. The first White Knight Chronicles is being bundled in with the second. The entire story campaing of the first available for people to play with! I think its a great idea! It increases replay value by a lot, doesn't alienate players new to the series and is great value for money. On top of that, the company is not going to negatively affect its sales. Rather, the allure of something "extra free" would entice more gamers to buy the game. I know it has me thinking about buying it and that is based purely on that one simple point (as I know it will provide a lot of bang for my buck, so to speak).
I know there are lots of games I would buy if the prequel was bundled with it as an extra incentive.
What do you guys think? Should this be encouraged by more companies?
