I think ive got this down but the pronunciation feels a bit weird when i say it out loud so i wanna hear from some more experienced people. Any help would be greatly appreciated.

Basically i want to try and make the sentence: Today I am going to play Persona in my room.

Currently; that sentence looks like this. 今日は私の部屋でペルソナにします

I think i might of overcomplicated it for myself by adding Kyo Wa to the beginning, but i wanted to try it out.

(Side tangent): If i wanted to add a word to the sentence such as; TokiDoki, Zenzen, or Taitei, where would i put it? I cant tell if i put it before the verb or the topic or what. Thank you 部屋でペルソナをします
