Arabians Lost: The Engagement on Desert is an action-adventure game for PlayStation 2. Players assume the role of Aileen Olazabal, the princess of Gilkhatar. Desiring a life free from royal obligations, Aileen enters a wager with her parents: raise 10,000,000G within 25 days or comply with their arranged marriage plans. The game features exploration, quests, and challenges within a vibrant desert world.
Aileen Olazabal is the only daughter and princess of Gilkhatar who wants nothing more than to lead a normal life and not be a princess. However, nearing her birthday, the King and Queen decided that she should marry and chose a husband for her.
Wanting to live a normal life (which includes having a normal romance, falling in love, etc.), Aileen refused. This lead to a wager between Aileen and her parents; if Aileen could raise 10,000,000G in twenty five days, she's free to do what she wanted. If she failed, then she'd have to do what her parents had planned.
