1) "Is it really important to have a game concept for a game?" I mean ask yourselfs, if you still wanna change and things in a finshed or almost finished game you would have to recreate or modify the concept. Or what if you would have a medium or small project? Would you still need a concept or not?
2) And to concept what kinda phases are there? Would there really be only 4 Phases or more? Is it like changeable like the HERMES Concept for IT project or is it something fix you just have to follow to have a successfull game?
Thank You For Your Feedback
EDIT: Rewriting for the For Beginners forum. Sorry about that.
1) You need to know what kind of game you are making. You cannot suddenly decide "We're almost done with this shooter, let's turn it in to a side scroller!" Or perhaps say "My driving game is almost done, i'm going to change it to a 2D puzzle game".
For medium to large games there is much more involved. There are game design documents that evolve over the life of the process. There is a lot of work involved to come up with a very clear purpose of the game. Usually this is best expressed as a single statement or slogan, every other design can be approved or denied based on that single statement.
For a hobby game, do what you want.
2) There are no required stages.
For medium to large games, this is just one piece of the business operations plan. It is common (but not essential) to have a concept phase where the concepts are reviewed and the details worked out, a prototyping phase where the idea is vetted for actually being fun, and lots of ideas are experimented with and discarded. Then you have another phase, perhaps called pre-production, where core components are implemented. This again gets tested and vetted to ensure it is fun. Then another phase, production, where the game actually gets made. This can include main development, feature complete, alpha, beta, pre-final, and final stages. Then there is post production where everything gets packaged up, distributed, sold, sold back and returned, players are supported, and more.
For a hobby game, do what you want since you will likely never sell it. If you intend to commercially release it, you better develop a solid business plan before developing the game.
