Well, Privateer was very open-ended, although it had a main storyline (which is present in the remake). I would say that the Privateer mod is more fun to play than Vega Strike right now. This is mainly because the gameplay is inherited from the original Privateer, which was fully developed, whereas the Vega Strike gameplay is still a work in progress (things will probably be better once the stats are completely re-balanced, preceding the next release). However, the graphics for the privateer mod are also inherited from Privateer to an extent, so you will generally find the graphics to be better in Vega Strike.
while talking about wing commander I saw on amazon that the first three were T but there was a collection of the first three games that was M anyone know why?
One wing commander game has only one third of the required killing to get an "M" rating. Thus, sold separatly, they can each get a "T" but if delivered in a barrage, they can destroy the goodness of even the most innocent youth. A force this dangerous must be regulated!
It's like gunpowder, the components don't work on their own, but if combined correctly and in the right proportions, hell is unleashed.
