Ya - it is pretty sparse in Animal Crossing in April. Given that this is 1.9, I'm holding out hope that the 2.0 version will have some gameplay additions. I would just like to see some new milestones added to fishing, bug-catching and deep sea critters, and maybe some new and interesting things to build with the millions of bells that we have sitting in our bank accounts.
I have always wondered why we get so many different types of flooring and wall papers when our only option for using them is a 6 room house. It would be nice to see some sort of new building that we could customize with all of these wall papers and floors.
And, the data mining that shows that farming and cooking might be in the game also sounds promising. Being able to invite our villagers to our houses and cook for them would be pretty fun. I would definitely take that through its paces a few times.
