Art Director

• Lead Game Design Director for a new cross-platform 4X title at Goodgame Studios. Define core loops, FTUE, and metagame systems; collaborate across Monetization, Product, and Marketing. Create a cinematic and intuitive FTUE that blends gameplay, narrative, and brand identity. Translate product goals into systemic game design, aligned with monetization and user lifecycle stages.

Collaborate closely with Marketing and UA teams to align FTUE and content flow with campaign messaging and conversion goals. Set benchmarks for design documentation, system clarity, and interdisciplinary collaboration. Ensure that the game performs at the level of genre leaders – in both emotional impact and gameplay structure. This is not a people management role; a high-impact, hands-on position.
