Digital Hotel
(unofficial)
This is the most accurate version of Hotel made for Windows.
It is developed with Visual Basic so the graphics are simple and flat, but the good side is that it's really easy to use.
You can save your matches and load them later too.
A useful function is to see a graphic of the trend of player's money through the match.
Helpful for lonely players, because it lets you challenge with the CPU up to 4 players. Worth to try only for Italian players, but it had to be released in English too.
