5 reasons not to rush to Unity

Here are some possible reasons to stay away:

1. These are proprietary platforms. There are people and organizations who prefer to bet on open source software — because of cost, or because they can adapt it to their own needs.

2. You’re stuck with one vendor. You can’t move a Unity scene to, say, Flash or HTML 5 and WebGL without recreating it from scratch. And you can’t move a Jibe environment to Unifier without re-importing all the original constituent meshes.

3. You need to have meshes. That means having professional designers create your content. Free items from the Google Warehouse or individual objects bought in online mesh stores will only take you so far. A school won’t be able to have its students and teachers to create what they need for their classes — unless they’re part of a 3D design program.
