Most one man shows should not be used for commercial games:
- one man means slow progress (how much can one person add and maintain)
- if the developer is a student, his free time will degrade - much slower progress than before
- no team behind him means he cannot delegate things
- during your hot game dev time, the one man engine could just dissapear...

If it takes two years to create your game, you need an engine which lasts even longer to be able to fix bugs which might be found by your customers later on.

If you just want to toy around with a game engine to create a "break out" clone, forget what you read here - otherwise you would be wise to use a product with wide support, great community, tons of tutorials and some great titles already on the market.
