RacerBG I only bought a license a few days ago, but before that I won a competition with a game I made in the free edition, I then used the money to buy the license. But the game was made with less than 100 events, in about 50 events, I managed to get the whole puzzle game done. The game is still under 100 events.
The 100 events can be a limitation if you aren't thinking enough on how to conserve the use of events, but it also taught me how to build events more wisely, using less of them to do more. Which in the end, is a good thing.
Having a short line which teaches people how to make a game with the same engine which is being provided free for you below you game is not really too much a limitation..
If you're a hobbyist who won't make a hundred bucks out of your game, the free edition is more than enough for you. If you buy a license, things get serious. I'd only have taken this jump if I'd realized I may one day use the engine to earn back more than that.
