I reckon many are feeling the same way, but most know it's important to deal with the core issues first, otherwise features are useless and no point throwing them into an engine that doesn't perform well enough to handle them.
A monthly release with all new features was in fact going nowhere fast and causing more problems than was worth it, I for one would rather see it being released with working features than hacked in and half working, for that reason alone I can wait
It's not a good idea putting unneeded pressure on TGC to release Beta's before they are ready, it has caused them enough grief as it is by doing this and far more damaging to the product.
I am sure once performance work is completed you will see more of the features you are looking for on a more regular basis. Still you wouldn't be creating a finished game for some time even with a finished product, it takes a lot of work, specially for a single person, but you will be able to do it as development goes along
If you check out the Classic Showcase board, any game worth talking about wasn't done overnight. Same applies to the development of this product, you don't want to be jumping around getting everything half done and nothing finished.
Where have you been the last month?
