Three weeks of playing a play to earn game: this is my first impression about Upland

In the last period, as I am more and more interested in crypto, I discovered the NFT concept. And by searching in detail, I also discovered the concept of Play and Earn games.
Play and earn is a “new” concept of online games, that allows to play and earn real money. But you don’t gain real money directly (like lotto, gambling, and other classic money games). You earn NFT (non-fungible tokens) that you can sell for crypto and then you sell your crypto for classic money.

Upland

Upland is one of these games, this is how it is introduced on their official site:

Upland is the earth’s metaverse mapped to the real world and accessible via web, iOS and Android. In addition, there is a “real economy” that is sustained by the players via the market forces of supply and demand. Upland is built on the basis of three key pillars: Play, Earn, & Connect.

So to summarize, Upland is like Monopoly. You can buy and sell virtual properties. The main “currency” in upland is UPX, it allow you to buy “virtual” properties. When you own a property it allows you to earn money.
There are two levels in upland: visitor and uplander. when you are a visitor, you need to renew your visa every 6 days.
