Javier, you had any thoughts about making any scenery - airports etc? Perhaps a wide coverage of major airports in moderate detail would sell well in x-plane and be interesting to make? Something like "Major US airports" (KJFK, KLAX, KDEN, FSFO, KMIA...) or "Major European Airports" (EGLL, LFPG, EDDF, ...) etc I don't know how interesting you'd find that compared to aircraft, but it's something sorely missing.
