What game dev project completion strategies actually work?

[Michael.M]

I have about 5 half finished game projects sitting on my hard drive. I'm good at starting things but terrible at game dev project completion. What strategies have actually helped you finish projects? Looking for both planning approaches and execution techniques that lead to completing game projects successfully.

For game dev project completion, scope is everything. My rule: if I can't describe the complete game in one sentence, it's too big. Tiny scope means you actually finish. My last completed project was a spaceship that shoots asteroids and gets faster each level." That's it. And I finished it.

I use the vertical slice" approach for game dev project completion. Instead of building all systems partially, I build one complete, polished section of the game. A single level with all features working perfectly. This gives me the satisfaction of completing game projects while keeping scope manageable.

Deadlines are crucial for game dev project completion. Game jams are perfect for this. 48 hours to make a game forces you to make decisions, cut features, and ship something. Even if the game isn't great, you practice the complete cycle from idea to finished product.

I track my game dev project completion with a simple checklist: concept, core mechanic, basic art, sound, polish, release. Each project moves through these phases. Seeing projects stuck in concept" phase for months motivated me to either finish them or officially abandon them.
