"There are many elements to consider for each game, and I believe those elements change depending on the game, the platform, target audience, and purpose. The three elements which I focus on the most are the UI/UX because those are what makes a game enticing and fun to play. I also focus a lot on sound. If the music is lighthearted and fun, it makes a significant difference to a player, over annoying sounds. Lastly, I believe that a successful mobile game must have a solid pricing strategy. Freemium or pay-to-play models are very lucrative for many games right now."
