Dungeon Keeper vs Kingdom Classic
Dungeon Keeper
Dungeon Keeper is a somewhat tower-defense-like strategy game that allows you to build your very own dungeons, staff it with a plethora of demonic minions, and set off to raid other people's dungeons to win some sweet loot. Play as a ruthless dungeon keeper as you do your best to stop these pesky adventurers from stealing stuff from your dungeons. Get creative and devise the most painful ways to deal with these hapless heroes with the many tools at your disposal like traps, hordes of demons of all shapes and sizes, and more.The PC version of the game also has a special multiplayer feature where you can play with up to 4 of your friends and challenge each other's dungeons for the rights of being the best dungeon keeper. Of course, the reworked mobile versions are already multiplayer games whereby you'll get to raid anyone's dungeon and everyone will get to raid yours.
If you liked games like The Mighty Quest for Epic Loot, Dungeon Keeper is definitely right up your alley. If you want to play the classic version, then you can get the PC version; if not, you can give the mobile game a try instead.
Kingdom Classic
Kingdom Classic is a pretty challenging and yet entertaining, 2D game that also happens to be one of the more innovative tower defense games in recent years. Developed and published by indie companies, this game puts you in the role of a crown-totting king or queen who is setting out to find a suitable spot to settle down and build his or her own kingdom from the ground up.There aren't a lot of kingdom building in this game though. Aside from upgrading your main "base" which starts off being a simple campfire, you will only build and upgrade certain structures like farms, walls, and towers. The game also uses a really simple coins-based system where you rely on the coins you earn to do practically everything, from converting wild men in camps into your kingdom's loyal subjects to powering up special stats-boosting shrines, to unlocking new stone upgrades, and even to upgrading your very walls.
Your kingdom will be under constant attack by creatures from otherworldly dimensions every night, and hopefully by then, you would have some defenses up and ready. These creatures will become increasingly harder to kill, more in variety, and more in numbers, so you will need to ensure that your kingdom's defenses are sufficient to meet the threat.
Due to its difficulty, you might want to check out some of the guides out there after trying a round or two on your own, just so you won't pass up on this amazing game. Even with the guides though, you will still need to put in a good deal of effort and strategic thinking just to make it to Day 50 let alone Day 100. So, if you're a fan of tower defense-like games, don't mind pixel art, and enjoy a good challenge, Kingdom Classic is an indie game you will want to buy.
