Moomoo.io vs Tartaros Rebirth
Moomoo.io
Moomoo.io follows the incredibly simplistic style used in most IO games, but its gameplay is quite different from what you'd expect. Unlike having a similar gameplay to games like Slither.io or Agar.io, this game is more of a strategy game where you move around the map collecting resources to build a village of your own. You can then construct windmills to generate gold for you to use, but you'll have to defend your windmills from hostile players... which are everywhere on the map frankly.It's a pretty intense multiplayer game, but it definitely brings a new form of gameplay to the iconic IO games genre. If you're interested to try it out, you can do so for free straight from your browser.
Tartaros Rebirth
Tartaros Rebirth is the revived version of the anime-themed MMORPG that was popular back in the 2000s, Tartaros Online. Featuring everything you know and love from back in the day, this game has something new to offer as well, such as brand-new storylines. Like the original, you'll get to play as one of nine unique characters, each with their own personalities and skillsets. You can switch between them while you're in town, but not in dungeons or instances. Questing is the main way to level up in this game and the grind is real. However, there are tons of places for you to explore and you can even use higher level characters to complete quests for your lower level characters to turn in.The combat system is rather clunky though, so is its controls with keys that you'll probably have to rebind. Battles are played out in a semi-action-based manner, but since you can't really dodge, block or dash away from danger, all the "non-action" can be a bit underwhelming. Not to mention, the graphics isn't updated somehow and although it may have been acceptable back then, it is definitely not something that will appeal to players in this day and age.
So, in short, Tartaros Rebirth is a great anime-themed game to play, despite sharing many similarities with Dragon Nest, for nostalgic purposes but if you're simply looking for a new anime game to play, you might have a better time playing Lineage II: Revolution.
