I planned on buying the full version but...

I really didn't expect to like this game, but it was very fun and original. I could tell a lot about the full version by playing this, and I'm thinking that it's probably even more fun than this game. But one of the things I noticed about this game and the full version is that it hasn't been upgraded in several months. It's almost like the developers made the game, fixed a few bugs, and left it to just collect money in the app store. Even though I loved this game and thought it was worth 5 stars, I would definitely prefer to spend my money (even if it is only 99 cents) on a game that is going to get better and have at least semi regular upgrades and additions.

Click yes if you think that ngmoco should add more levels to the full verison of this game. Maybe then I'll buy it :/

Great Filler for Star Defense!

Although I was expecting all the planets to have a "before the invasion look" as did Outpost D-13, it is a great filler to see what things were like before the war. Here's a few suggestions: make an option to sync the free one with the paid one to get the before the war look of each planet, make a "Star Defense The Aftermath" to feature planets after the war and cleaning up the invaders. Overall not much to expect from this if you have the full version. There are some minor issues like Commendations from the full one syncing with this one and the Plus+ icon out of place.

Sign up to play?

Was curious about the prelude so downloaded it. I was shocked to find that you can not play without a Plus+ account. I feel rather offended by this. I'm not into online gaming so I never sign up for these things. Not giving an option to do so or not says a lot about the company and how it views it's customers. This is a big FAIL and the first time I ever had to give a game a rating of 1 (because it won't allow 0) here in the AppStore. I refuse to play StarDefense Prelude until Plus+ is made an option.

To make it clear, I do have a Plus+ account from when it was first debuted in the AppStore to try it out. Since I don't compete with other players I don't use it. That's my choice and not my opinion on the service. Sign up for Plus+ should be a choice not a requirement.
