Shadowbound vs Tartaros Rebirth
Shadowbound
Shadowbound is a browser-based MMORPG by R2 Games that provides players with a range of features that are customary in browser-based MMORPGs, such as item enhancement, all-powerful guardians and mercenaries that can be recruited to join your team, mounts, pets, PvE dungeons, PvP arenas, wings, auto-routing for quests, guilds, and auto-combat, as well as a cliche storyline. Like most of its simular games, you can expect tons of fun timely events to help break the monotony of simply leveling up and upgrading your team of characters.The thing is Shadowbound doesn't really offer something... anything... that can help it gain extra recognition from even among R2 Games' other casual MMOs. This is quite unfortunate because this is a rather decent browser MMOPRG. That said, if you are itching for a casual MMORPG to play, you might want to check out Shadowbound. It can definitely help you scratch that itch away.
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.
