Sirus Gaming PH:
To sum it up, Trulon is an alright RPG. It does well with it’s innovative combat in an attempt to stand out from the crowd, but is unfortunately bogged down by its generic cast, uninspiring fetch quests, and being forced to go through all of it with your character’s walk speed. That said, it’s still an enjoyable title for its cheap price point and its availability on the mobile platform.
Taking the simplistic and inevitably addictive nature of card games and incorporating them into an RPG sounds like a great time to be had, giving the feeling of, "What if Yu-Gi-Oh! was an adventure game or something along the lines of the Pokemon Trading Card Game on Gameboy Color, but for the modern age on current-gen consoles", and while Trulon: The Shadow Engine does well to give a bite-sized RPG, its use of cards isn't so much a focal point as you'd expect, and comes with a lot of technical mishaps along the way.
COG writes - Another mobile to console port that isn't worth what they're asking for, Trulon: The Shadow Engine is a wait for a sale kind of game at best.
XBA says: A great backdrop and story, but glitches and unfair difficulty hold this back from being great.
