Hey, you missed out...

Understandably, we're likely to have missed out on some notable game engines but we have been careful in selecting those that are free to download and are not trial based. Some of these do include additional license fees and royalties for commercial use but ultimately they are free to help you develop and hone your skills in game development.

However, feel free to let us know at @TechnojobsUK of any useful (and free!) game development tools.
