Mac (10000 programs)

Pros: High customisation; change anything from colours to blur effects. Screenshots can be exported to PNG or JPG format. Small price is highly preferable to hiring an expensive professional. Save your user settings as a template for later.

Cons: Only for mobile devices; not available for desktop. Some may prefer to pay for professional service if they don't have time or patience. Price only worth it if you're passionate about creating your own material. Takes some concentration to get the hang of each setting.

Pros: Upgrade buildings as you progress. Does not punish short-episodic play. Win up to 30 in-game trophies. Each episode has its own story.

Cons: Demands you promote them on Facebook to progress through levels. Massive amounts of waiting and grinding. The cartoon-graphic styling looks dated and slightly pixelated. Some final-enemy battles are very similar.
