Personally, I would like to see Russia. We have a lot of different airports: from the newest ones like Rostov (ROV) to the old ones like Grozny (GRV). In addition, there are joint-based airports like Novosibirsk (OVB). We have a very diverse landscape, from the highest mountains in Europe to the steppes, from the cold Arctic to hot deserts, from one of the largest cities in the world (Moscow) to dense forests).
Along with this, I would like to see more Russian aircraft (civilian Superjet 100, promising MC-21, or combat Su-30, Su-34, MiG-31, Tu-160, or Ansat, Mi-8, Mi-26 and Mi -35) or Russian liveries for existing aircraft (Russia, Transaero for 777 and 747, S7, Aeroflot, UTair and DonAvia for 737-500, Yakutia for Q400, Nordwind, Ural Airlines for A320 and many, many other liveries).
