Dreamfall now an Xbox Original

Trust me, unless you computer is a relic of the 80's, you will have no problems running this game. There is a bare minimum of geometry as the majority of the art assets were either pre-rendered or FMV. There's nothing in this game that will come even close to pushing your computer.

That's not to say it's a bad game. Far from it, it's one of the best adventure games ever and has one of my favorite game stories. Dreamfall will be a MUCH better game had you played the original as it's the second part of what will (hopefully) become a trilogy*.

Would you have wanted to watch the Two Towers without having seen Fellowship of the Ring? Or The Empire Strikes Back before Star Wars? It's the same thing here. Story is the main draw for these games and the backstory of The Longest Journey will undoubtedly enhance the experience of the sequel. There are also moments in Dreamfall that are meant to be really, really cool but will be lost on those new to the series. You don't want that do you?

*Unlike a trilogy however, there aren't going to be three games. The Longest Journey was the first chapter. Dreamfall is the second, however that was only the first part. The next game will conclude it, i.e. part 2 of chapter 2. The final game will be the final chapter which then brings the total amount of games in the series to four. At least that's the plan. The games need to have sold well enough for this to happen. I would be devastated if Funcom never got the chance to finish the story. So BUY THE GAME. BOTH OF THEM. This is a story that needs to be completed.
