In 2017 Team Kirby Clash Deluxe was released for the Nintendo 3Ds, the first free-to-play Kirby game, and an upgrade of the subgame Team Kirby Clash from Kirby: Planet Robobot.

If you have never played the original subgame, the gameplay is basically a boss rush where you play with three other Kirbys. You can use four classes: Healer, tank, melee, and mage, but you can repeat classes during boss battles, so if you want a team of four tanks, you are free to do so. There are also RPG elements, like equipment, experience points, and potions that boost your attack and HP. So, to defeat later-game bosses, you'll need to buy better armor and level up a lot.

The problem is that you are playing a free-to-play game, which means that there is a currency you can only get in two ways: Using real-life money or grinding a lot. The currency is called Gem Apples, and you need them for everything. Want to buy a new weapon? They cost gem apples. You can battle a new boss? Well, first you have to unlock their level using gem apples. Want to buy a potion? They cost gem apples.

Now, to be fair, they are easy to get without spending money, as you get them when you get achievements, every 12 hours you get 5 free (unless you upgrade your tree, but you need to spend actual money for that), using passwords (although they are very limited, as most of them have expired) and playing in multiplayer. But because the equipment is expensive and bosses get a lot harder if you don't have a decent armor/weapon, you'll get stuck playing the same boss over and over, trying to level up and unlock enough achievements to buy a single piece of equipment decent enough to give you a chance against a harder boss.

This is extremely tedious, especially because you have a limited amount of energy that can only be refilled by waiting or using gem apples (obviously), so you'll battle the same boss three times, then wait some hours to do the same thing, and that will be your only goal in the game until you get the level or weapon you wanted. The only way to avoid this is to spend real money, and if you get lots of gem apples, you soon realize that the gameplay feels pretty repetitive when you can defeat bosses consistently. Not only the same bosses are recycled many times with minimal differences, but your move set is the same the whole game, the only difference being the damage you deal.

In conclusion, I'm sure the game is a lot more entertaining if you manage to play with friends, but unlike Kirby & The Amazing Mirror, which is very fun even if you experience it alone, here the core gameplay is tedious and repetitive, and with the amount of money you need just to get decent items, you could instead buy a better game.
