1. yes, just about all planets have elliptical orbits, i have made many of them in the past but they just dont seem to turn out right i have plans for making a system whith attraction and stuff but if i do then i wont get the nice shadows by the planets, hehe. thats why i made this, cool effects
2. i know, it irritates me to, but i also wantet to get big planets. the plan for this was to be a kind of space game where you could fly around the star system and collect resorces to save the home planet of some sort, thats why it is so big, but i understand now that i just could have put the planets closer together wont happen again!
to DualDesertEagle: if you dowload it and mark everything whith the box tool or something you will se what i mean whith non attraction based star system.
everything is mechanicly driven
