Today the first Topware games arrived: Enclave Gold, Gorky 12, Knights and Merchants, Jack Orlando DC and Septerra Core. Prices are 5€ and 5$ (checked by proxy). All games have german language support and many also polish (K&M, Gorky, Jack Orlando). The coming soon advertisement is still up and the Interplay promo goes the whole week.

Edit: And on the gamespage there is now a bonus field which shows what else is included.

What's Gold about Enclave Gold? It's got Shadows of Twilight banner on its page for some reason.

I asked myself the same question. Amazon comments says you only get some extra stuff like cards posters or posters, nothing really relevant to the game. Here is the topware page about the gold version: http://www.topware.com/en/enclave-gold-edition.html

So, I just noticed that Gorky 17 on DotEmu has 6 languages including English, Polish and Russian. Verily, the package is larger that GOG edition. The Russian turned out to be the good old localization by Snowball I grew up with, where the American was replaced by a Russian, the Pole by a Ukrainian and the French(?) dude became Estonian.
And it's $1 cheaper than GOG if you're lucky to pay in $.
Anyway, GOG hopelessly losing a sale aside, the version comes with 2 alternative exe files. One of them crashed under XP with GF9800, one of them didn't and let me use Software and D3D mode. Under Win7 it's still slow menu and slow game, if you pick RGB emulation with something like GF240M.
