Hi there.... Are there any novels in which there are multiple planets and MC has good abilities? I played Rogue Galaxy on my PS2 and was very fascinated by the idea of the game...but please avoid any romance plot if possible......... Star Rank Hunter was kinda similar to it and please suggest any novel similar to it.....
Emperor of The Cosmos might be similar to what you are looking for although it is more focus on Xianxia style cultivation and Martial Arts.
I Shall Seal the Heavens Xian Ni Swallowed Star Skyfire Avenue Against the Gods - I think... Stellar Transformation Though I don't know the novel or game you mentioned. The 2 in the middle are more sci-fi if that's what you're looking for.
If you like Star Rank Hunter, I would recommend Forty Millenniums of Cultivation and Cultivation Chat Group
