How are you going to develop it in? I suggest flash, its the most common form of tower defense games. People are not going to download a tower defense game unless its full on like the Monsters game for PS3 or the Savage Moon for the ps3... I suggest that you make distribute it to major Flash game sites like Addicting games
Yes, I'll be building the game in flash. I can do most of the art work but I would need lots of help with coding. I have some background in AS3 but I don't think it'll be enough to build this game. If anyone would like to help with graphics and/or storyline that would be great too!
I'm glad to hear there are some of you who are interested :]. I'm going to put together a little flash mockup of the game play later this week.
So before I get into more detail, this game isn't going to be played like a traditional tower defense. There will be a main character and you follow him through obstacles, somewhat similar to traditional Pokemon games and then mix it with the tower defense aspect.
I'm sorry if you don't get the whole image of the game. Hopefully after the mockup things will become more clear.
Storyline (rough idea)
Player is a pokemon trainer who comes back to his small home town and finds out that an epidemic has gone around that have made all of the towns people sick. You seek the elders for guidance and tell you that the only cure is from the tears of a pokemon which lives high in the mountains East of the town. As you journey out to collect the tears, you face tough obstacles.
Game Play
You start with 3 pokemon (Bulbasaur, Charmander, and Squirtle) which act as towers. As you defeat enemies you gain XP which can be used to evolve and/or level up stats. Each Pokemon specializes in an attack when you evolve the pokemon it's attach changes. i.e. Bulbasaur attacks with vine whip which attacks at medium range. When evolved into Ivysaur it's attack now becomes leach seed which is a slash attack that takes away life for a short period of time.
Those are some basic ideas of the game.
I'll be glad to hear any of your ideas or suggestions! :]
