This excludes mainstream games (looking at you, Sans, you magnificent big-boned boi.) For me, since I get frowned upon for mentioning the Game that Shall Not be Named, it has to be Terraria’s Moon Lord. I’ve been playing a lot of Terraria recently, (expert mode, to be specific) and I gotta say the Boss themes in there rival that of The Game that Shall Not be Named and heck, Undertale (though Undertale beats them both by Quality and Quantity, since it’s focused entirely on boss fights). For Terraria, the Moon Lord is THE ultimate boss. There is no more bosses to defeat (well, that you NEED to defeat) after him. Once you defeat him, everything, and I mean EVERYTHING becomes instantly farmable (except for maybe the Moon Lord himself) because of his drops: Meowmere, the best sword in the game (until Journey’s End that is), Luminite (allowing you to craft all 4 sets of the Endgame gear and the Drill Containment Unit), and his expert mode drops (ironically the lowest tier expert mode drops in the game) allow you to traverse the world way better and find enemies and items way more efficiently. There’s also the Lore behind it, which isn’t explicitly shown but implied heavily. The Moon Lord is the reincarnation, imitation, or new Iteration of Cthulhu, a product of the Cultist’s rituals, unless it goes deeper than that. You need to stop him before he gains full strength, because if you don’t it spells doom for the whole realm. You finish the fight for Terraria by defeating the amalgamation of all the Cthulhu bosses you ever fought, and when you do, it’s over. You won. No more bosses, and the world is saved. What’s interesting to me is how they’ll continue the story after that, because it has recently come to my attention that Re-Logic is working on Terraria 2, and aims to dive deeper into the lore and universe of Terraria (I wonder as well if they mean literally by going to space) with an infinite world. Sorry for the big post, and the delay. I became ill Friday evening right before I was going to make this post. [spoiler]The next chapter of [u]A Titan Rises[/u]’ deadline is tomorrow evening, for those wondering. I want to get that ball rolling and start on a Spooktober RP for those interested.[/spoiler]
