Program-Ace (Game-Ace)

Program-Ace started in 1992. Their game division is called Game-Ace. They handle complex technical projects for US and European clients. The focus is on simulation games and training tools where system integration matters more than graphics. 

They use structured processes and document everything. Other studios hire them when they need engineers who understand complicated systems and can work within existing teams. They also build gamified tools for military training, corporate learning, and marketing.

Services

• Serious game development for military, retail, and manufacturing training;
• Custom game development across mobile (iOS, Android), web, PC (Windows, Mac), VR (Oculus Quest, HTC Vive), and AR (marker-based and markerless);
• Immersive games, metaverse experiences, and gamification solutions;
• Cross-platform development ensuring compatibility and engaging performance;

Services include prototyping, cross-platform development, VR/AR, porting, and UI design. Since Unity is their sole focus, they catch things generalist studios miss. Most clients hire them for specific features or modules rather than full production.

• Unity porting across multiple platforms;
• Game optimization and performance tuning;

Key Factors to Evaluate Before Hiring

Choosing the wrong development partner creates problems. Portfolios show past work but hide how a team actually operates. These factors matter more.

• Technical Fit and Portfolio: Check their portfolio for similar games (genre, platforms). Avoid mismatches like Unity teams for Unreal or casual mobile devs for complex sims.
• Process and Communication: Ask about tracking tools (Jira, Slack, Trello) and main contacts. Prefer direct developer access and regular updates over account manager summaries.
• Team and Scalability: Confirm who will work on the project (senior vs. junior) and their ability to scale the team up during production and down afterward.
• Time Zone and Culture: Look for overlapping working hours and real-time communication. Evaluate how they handle deadlines and feedback to spot potential mismatches.
• References: Contact past clients to verify on-time delivery, feedback handling, problem resolution, and final product quality.
• IP and Contracts: Clarify ownership, code access, and post-launch support. Ensure the contract clearly defines IP, payments, milestones, and dispute procedures.

Conclusion

Good game dev partner matches tech to project requirements. Reliable communication and straightforward contracts. Evaluate them on portfolio experience that's similar, response speed, references for meeting deadlines and handling issues, plus IP rights and support after launch. 

A strong partner acts as an extension of your team. Provides specialised knowledge and adapts to how you work. Clear terms and a transparent setup make external development useful for flexibility and skills you can't maintain internally.
