This blend of gacha and tower defense works, but I'm not sure for how long
I love tower defense games, and I have a self-admitted weakness for gacha when it's done right, so of course Watcher of Realms was going to appeal to me! In this title, each of my towers was represented in the form of a character I could pull from the gacha and power up individually through leveling, equipping gear, and so on. It's sort of like Defense Derby, but with a more traditional (read: boring) high fantasy visual style.
