Operencia: The Stolen Sun Review: Clouded by Imbalance

Dungeon crawling, turn-based, RPG with a grid system for movement and severely difficult puzzles. That’s Operencia: The Stolen Sun. This may sound great to some and a pain to others. You’re tasked with finding the Stolen Sun (kind of randomly) and get to create your own character to do so. Along the way you’ll find more friends and create a powerful team. There are several levels with a limited amount of enemies.
You’ll be wandering around quite a bit, so it’s probably best you don’t have random encounters all the time. There are many secrets to find and you could drop hours looking for them. If you’ve ever played games like Myst, you’ll know how long you can spend trying to figure out a puzzle. Will you be sucked into a magical world of charm and find the Stolen Sun, or give up frustrated because you can’t figure out how to progress the story?

Wrap-up
A beautiful package of a game, Operencia is enchanting but clumsy. It misses as much as it hits the target of being a great role-playing adventure. There was one glitch that was alarming to me. On Atilla’s Tomb, there are sections that overheat my Xbox One X. It shut my Xbox off at least six times. Suddenly my fans would go crazy and it would power itself off. Turning it back on, I would get a message about overheating. It was only on that level but it scared me from playing on. I did battle through it hoping I wouldn’t ruin my console. I do not think there is this same issue for PC players. If you’re in love with the trailers and concept, you probably won’t be disappointed with playing it. If you don’t have the patience for puzzles that require hours of wandering around then avoid this at all costs because without a guide you’ll likely be stuck in many areas. I’m torn, I really am. While I am love stricken with Operencia, I also am tormented by its flaws.
