blotunga: Now that I joined the Dark Side and installed Uplay, I saw that Nuuvem has Anno 2070 complete for $6.4 or so. I have two questions about this:
1. Can the game be played offline?
2. Does it have the english version/are there any region locks or restrictions?
As far as offline goes; can't help you there personally, but reports on the 'net seem to suggest that it is possible to play offline, but that it limits the gameplay experience.
On the topic of languages: According to Nuuvem's own page, the version they sell has English, German, Spanish, French, Italian, Polish, Russian and Czech interface language support. No mentioning of supported Audio or Subtitle languages though. I don't know the game so I can't tell you if that means there is no language-specific audio or subtitles or if it means that those languages are not supported.
As a side note, the games I bought from Nuuvem in the past always at least had English language support for all relevant parts.
As for region locks; Normally, Nuuvem either mentions those on the game page in bold red letters or, (if you're not using a VPN,) region locked games should be listed as 'Unavailable' (check Sega's Football Manager series for instance).
