I want to purchase a new laptop for casual and adventure gaming. I have a desktop but I want the laptop for the portability. I'm looking at the Alienware 17 but I'm afraid there may be a problem loading games. I like games such as the Dreamfall series, Syberia, Darkfall etc.. I just purchased Jack Keane for the second time.
If you mean the ones herehttp://www.dell.com/us/p/alienware-17-r3/pd
They shouldn't have any trouble with Dreamfall Chapters.
The 2006 version of Dreamfall may or may not work depending on which version you have. Download versions should work, but some of the disc versions had DRM that Windows 10 will block (so the game won't start).
If you have the disc versions of Syberia, they have SafeDisc DRM and won't work on Windows 10. You'll have to get download versions.
Dark Fall 1 and 2 have more than one disc version. GOG lists the first Dark Fall as compatible with Windows 10 but not the second. I don't know if that's an omission or not.
GOG's version of Jack Keane is listed as compatible with Windows 10. If you had a disc version, it may be blocked by the DRM.
