What’s the best way to create energetic game voiceovers with Genny?

I’m working on a small basketball game project called Bills Must Be Paid, and I’m experimenting with Genny for short intro lines, commentary, and promotional clips.

For game-related voiceovers, is there a recommended voice/style or specific settings for making the speech sound more energetic and natural, rather than like a typical AI narration?

I’d also be interested to know whether anyone here has used Genny for game trailers or gameplay videos and what settings worked best.
