If you liked Uplink, you will definitely like Codelink v2, which was initially designed to be an Uplink 2 (although the developer is not related to Uplink), it became something way more than that, its great.
And if you want something more advanced, you wanna create your own tools and programs ingame, try Dark Signs, a pure awesome console based game with a whole lot of different commands. If you don't know much about programming, this might be a good place for you to start getting some programming logic. And if you already program, you can use some logic to create a whole bunch of stuff
