Selected Projects

Indie Games Recommendation

Indie games often lack visibility as compared to top-selling games due to their limited marketing budget and the fact that there are a large number of indie games. Players of top-selling games usually like certain types of games or certain game elements such as theme, gameplay, storyline. Therefore, indie games could leverage on their shared game elements with top-selling games to get discovered.

  • Tech: Python, Scrapy, Pandas, D3.js, MySQL, AWS RDS, AWS EC2.

What are hackathon participants talking about?

A topic modeling approach using Latent Dirichlet Allocation (LDA) and several natural language processing techniques to identify the challenges, lessons learned, and future goals described by the participants of hackathons.

An Empirical Study of the Characteristics of Popular Game Jams and Their High-ranking Submissions on itch.io

Game jams are hackathon-like events that allow participants to develop a playable game prototype within a time limit. Having a high-ranking game is a great bonus to a beginning game developer's résumé and their pursuit of a career in the game industry. However, participants often face time constraints set by jam hosts while balancing what aspects of their games should be emphasized to have the highest chance of winning. In this project, an empirical analysis of 1,290 past game jams and their 3,752 submissions on itch.io was conducted to understand better what makes popular jams and high-ranking games perceived well by the audience.
