Good artwork, sound effects, OSTs, animation, etc are catalysts for the gameplay to truly flow or have that satisfactory punch. Theyre like the spices you add to your grilled chicken to make it tastier.
Answering your question, yes, because gameplay is the core. However, even hiring some ringling undergrad interns can do a better job than that.
The spices you add will depend on the meal. just like the animation, tracks, and sound effects will depend on the gameplay, scenario or moment. If this is some turn based rpg that's totally fine. If it's some silly RTS, it would be fine. If it's a fighting game, then obviously not because that demands better frames.
In conclusion, The case scenario at hand matters, and this is a shit low effort thread for not even elaborating on what type of game this would be.
