I've no impact on what does/does not get ported by LGP. I only am a developer consultant for them in the first place and I'm off task, waiting for final release on one title and doing a bit of problem clean up for another right at the moment.
I know you're mostly kidding, but if you want Sacred 2, you're going to have to be good folks and buy Sacred Gold. It's been done quite well and I've been enjoying the purchase I'd made a while back. (Yes, I have to buy the titles I didn't have a hand in the making or maintenance thereof...) What was told to me is sequels are a subject of discussion with studios and publishers- but only if there's a sound enough deal for the first title.
