I hardly think the game you list qualify as budget games :P
And your original post in this thread never mentionned budget games in a known franchises...
I agree being less dependant on a particular IP is a good idea but you typically do that by trying to develop new successfull IPs and most of the time developing a new IP that will be dureable is a very significant investment, no matter what the target console is ( with marketing costs not negligible at all compared to development costs).
And wether we like it or not, one way developers have used to secure IPs and ensure their success is by pouring a lot of money into their development, making sure that the investment necessary to replicate those would discourage the competition ...
Why do you think there haven't been more successfull GTA, Wow, FF copies in the market ?
Because they cost a fortune to make and part of that cost is there to ensure they are not copied... ( that money isn't wasted but a lot of it is spent on things that really are not core to the game but end up being a differentiator).
If you could make FF for a few million bucks, the Japanese market would be flooded by FF look alike ( especially for a serie which resets at every new episode).
I mean, just look at Guitar Hero and Rockband.
These are games that are hugely successfull but costs very little to develop...
End result ?
Both are pouring millions of $ into exclusivity contracts to try to differentiate each others and stay ahead of the competition........( and prevent more players to enter the lucrative market segment they are in).
Same thing with Madden. Each new iteration really can't cost that much to develop, but there are huge exclusivity costs associated to it due to the contract EA signed with the NFL.
You just can't have a very lucrative product on the market without someone trying to copy it.
One way companies everywhere in the world have been using to prevent competitor to jump in is to make the entry price very steep, that and building a brand name as strong as possible.......
The issue with cheap casual games is that they neither rely on strong brand name or steep entry price so if they prove very lucrative the competition will do them too and the market will get flooded...
