OK, I'm thinking about how to approach a theme for a potential match-3 game. The game would be in the vein of Bejewelled, JewelQuest, Chuzzle, Magic Match, et al, but hopefully with enough new twists to be interesting (the core object manipulation mechanic I have in mind is fresh). Anyways, there have been a few games of late that have done their theming/object choice a bit differently than games from a few years ago. Bejewelled had a very basic theme, with the same set of objects (gems) throughout. The objects, while nicely done, were simple and solid colors. Very clear for quick matching recognition, but maybe not as interesting as possible alternatives. Games like JewelQuest and Big Kahuna Reef had more interesting objects, that tied in nicely to a background theme, but the objects were a bit more difficult to differentiate than Bejewelled's. Magic Match (and I think a few others), changes the object set every few levels. This keeps the graphics fresher, but on the other hand, could cause players to be less familiar with the objects being manipulated. I was considering all of these options, as well as one variation on the Magic Match idea - different sub-themes within an overall theme. Perhaps the overall theme is food, the sub-themes are different nationalities/cuisines (Italian, Chinese, Mexican, Seafood), and the individual objects are specific dishes/items associated with that cuisine. One sub-theme is used for an entire series of 6-8 levels (with a corresponding background). The downside is that there may not be enough overall coherence. Thoughts on: Colorful and basic versus more detailed and harder to distinguish? Changing groups of objects/sub-themes every few levels? Other ideas?
