Aside from missing a few odds and ends this package already contains an impressive assortment of tools for building many types of games. The space/sci fi kit is huge, it also has things like map builders and "snes looking sprite" character builders. My only complaints are that the game kits are not fully fleshed out, so you will not be able to get 100% of your resources from this.
With that said, just some amateur GIMP/Photoshop skills and this package will keep you busy making custom game content. It all fits togethers like legos. I literally just drag drop things into my layout editor. I really like it, and I'm excited that they will add more.
Massive space set, great quality, lots of animations, ships, parts, backgrounds, etc all look great at 720p
Assortment of things that are not as expansive such as a map builder, rpg icons, some avatars.
The only downside is that things aren't fleshed out. Sprites have walk only animations and the ground builders do not match the art style. Creating these things would take considerable work for an amateur. The space kits has more ships than necessary but lacks some things like icons for common gui elements or space inventory. You still have to get your elbows dirty if you're looking to complete a game.
If you're sick of being uninspired by using your own programmer art, I highly reccommend this. No worries about licensing, and it's very flexible. At least I'm having fun.
