Some weeks ago a colleague recommended me the browser game Space-Pioneers.
I'm still playing it and have some fun. A classical "produce resources, build something, defend and fight" game. Placed in space (hence the name :-)
First you start with just one little planet and enough resources to build mines for metal and crystal.
Later you control 9 (13) planets, have space ships, and act like a trader or warrior.
You can find me in Galaxy 4. My name is Lispstein.
I get some premium points when you subscribe via the Galaxy 4 link above. If you don't want that just go to Space-Pioneers and select any Galaxy you want
When subscribed you start on one planet in one of the many solar systems in the galaxy. There can be other players in the same solar system, too. Don't be afraid. After the first few possible things are built you have to wait.
The more resources are needed to build something (buildings, ships) or to research some interesting topic (espionage, weapons, etc.) the more you have to wait. Not just a few minutes. It can be hours or days.
But that's what that kind of browser game is all about. You don't have to sit in front of you computer for very long. You start up your browser, make some moves and actions, and then go on with you work/life. Ideal game for the lunch break and many short playing times.
