Definitely too much to collect. You can collect steel just from 3 or 4'th system (and some planets) but always it's not enough.. I'm at 29lv and I spent on this game 2~ weeks. You can say that point of this game is collecting materials.^ I would like to say about something else. At a higher level to get the next one you must perform missions, but often system gives those that do not give almost experience (on low lvl). It is really a waste of time.
