Digfender vs Rise to Ruins
Digfender
Digfender is a fun and challenging tower-defense game that, unlike many other games, is set underground. In this game, your ultimate goal is to protect your castle while digging a way down towards a cavern (possibly containing treasure). However, as you dig, creatures that have slumbered in the frozen ground will be awakened and they aren't happy with the rude awakening.In terms of gameplay, this game is intriguing to say the least, because you not only get to dig the path in which your enemies will be using; you will also need to be strategic in the placements of your towers. Towers come in many different ranges and damage capacities, allowing you to mix and match them until you find the perfect combination. Of course, each tower can be further upgraded and augmented, via support towers, giving them high damage, longer range or even faster XP gain so you can level them up.
The different types of enemies, along with their unique set of strengths and weaknesses, also provide you with some extra challenge. What's most interesting, however, is the fact that you can replay a level to collect a special token called a Relic. Relic tokens can then be spent in the special upgrade tree in the game.
All in all, Digfender is a fantastic tower-defense game that is as fun as it is strategic. If you're a huge fan of tower defense games, this is a game you'll want to try!
Rise to Ruins
Rise to Ruins is a godlike empire-building strategy game that incorporates some elements of tower defense (during night time). Inspired by games like Towns, Gnomoria, Banished and Dwarf Fortress, you will need to build a thriving empire, recruit new nomads to join you, manage your empire's resources, and ensure that your people are content in this game. During the night, however, enemies will start hammering at your gates, and as such, set up proper tower-defense-like defenses to funnel your enemies into easily manageable "slaughter zones" as well as appoint guards to patrol your empire's parameters.There are also tons of fun little features that made this game so engaging to play, including your special godlike powers which you can use to help your little people survive or to cause them a huge amount of distress, and how the creatures and people in the game react to the presence of godly powers. You can even completely change the landscape of a map if you wish. The game has a ton of maps and game modes, even in its early access form, for you to play around with as well!
Rise to Ruins is still a work in progress but the game seems almost completely done and ready for launch. So, although it's still technically in early access, you can rest assured that the game is in its playable stage of development - you can immediately dive right in after purchasing the game!
P/S: There's also a trick that you can use to stop enemies from proliferating at all on the map you play on if you fancy a peaceful sort of game.
