It's about monstrous (and perhaps cute) "Pocket Monsters" being forced to fight each other. You train your Pokemon much like you train party members in a traditional RPG. The combat is turn-based, and heavily reliant on a "rock-paper-scissors" style of gameplay where a certain kind of attack is effective against certain Pokemon, but your Pokemon is also weak against some kinds of attacks.
It's well-loved because there are a large amount of Pokemon, leaving opportunities to create your own ideal Pokemon team. Over the years the games have become larger, more content-filled, and strategically deeper. The DS versions feature online multiplayer, though the local multiplayer element of trading Pokemon has existed since the first game. Pokemon has a fun formula. Simple as that.
