Monopoly was actually my favorite game when I was a child, but if you were lucky enough to be the first buying the expensive properties you will simply win easily.
With risk, there is always a chance of losing even if you are winning, because the other players can simple decide to attack you to level the playing field
Monopoly was also my favourite but my dad was super competitive so when I played at other people’s houses I would be used to pumping price through roof to give someone a house that gave them the set etc and they would just give it me for face value so I would win on like 5 rounds but without any real competition funny how everyone was taught to play so differently lol
