Thank you odeonx, and welcome!
1. I do have this planned, but it will be a significant effort, and believe it or not you're the first to volunteer to translate. Still, that is great to hear; I'll bump the language packs up on my list.
2. MobyGames does not want to share their data (existing scrapers do this against their will), and thus scraping the web is the only way to do it. Unfortunately I'm not sure MobyGames will ever happen due to their policies. However, more scrapers are certainly planned.
3. All is planned.
4. Good idea on the new image types, noted.
5. Planned.
6. Region is new, added to my list.
7. Planned.
8. Planned.
9. Planned and in development.
10. Already implemented in the premium version.
Thanks again odeonx!
