Pokemon Emerald Rogue is a rogue-like game. You start in a zone where there is an area called the Hub.
The Hub is where you do your things like buy items, store your Pokemon, change your team, and others. When you leave the Hub, you choose which routes you go, which are procedurally generated.
Every time you enter these routes, you can encounter different Pokemon and decide whether you want to catch them. The end goal for each adventure you do is to get a Badge.
If you don’t get the Badge, you can go back to the Hub and get stronger. Continue doing it until you get all the Badges which will take some time since the game scales in level. You can also do quests and get rewards to help you get stronger and get further in the game.
A lot of the things are randomized (Pokemon, areas, trainers, etc)
