ArcheAge and you don't mind cutesy graphics, you might want to check out XLGAMES' ArcheVille. Oh yeah, you'll also need an iOS device (an Android version is in the works).
What exactly is ArcheVille? It's a farming- and minipet-based mobile game that ties into XL's upcoming sandpark title. MMO Culture reports that gift exchanges are possible between ArcheVille and ArcheAge, though we're not sure if that functionality will work for English-speakers just yet due to the latter's Korean-only client.
In any event, ArcheVille is currently available in English and viewable in the App Store. You can view a gameplay video after the break.
