Modern, strategy / resource management games are often called Euro games.
These games are often 90-120+ minutes, depending on the number of players.
Several aspects of these modern games set them apart from "Monopoly".
First, while there is some degree of chaos (randomness) in the games, winning requires planning.
Second, there are generally multiple paths to the victory conditions.
Third, there is some mechanism in the game to force it to end, resulting in games that don't last forever.
