Though age also matters, I believe reputation shouldn't be based on the age of a platform. There might be a platform that was launched last month or a couple of months ago but has been operating very well and its customers might have no complaints regarding anything, this also makes the platform reputable, and an old platform might decide to start acting weirdly all of a sudden and stop paying users what they owe them and might even shut down their services without any notice, this happened recently with a casino on this forum I won't take the name.
We cannot deny that the age of the casino platform is very important to consider before we decide to play on that platform. Because of course a casino platform can last for years because they have a good reputation and really maintain that reputation. Because if the platform does not have a good reputation and does not behave fairly towards its visitors by committing fraud, perhaps they would have closed long ago and would not be able to compete with the newest platforms. So if we decide to play on a gambling platform that has been around for a long time, it is a wise decision to make.
