Sure PM_ME, no problem at all. The game is packed with missions, lore, boss fights, engineering, scavenging and will play like a full-featured RPG. If you play through quickly, do some missions, some engineering and just try to beat it fast as you can on normal, maybe 3-4 hours. Do all missions, get the achievements done, play on hard after engineering two mod slot weapons, with tier II mods and you are looking at 5-7 hours depending on play style. It's different for everyone of course. Here is a link to an almost hour of game play and it is only the first level. https://www.youtube.com/watch?v=9zGTrEl0upY You can always go back and engineer the best weapons with the best mods to get ready for Episode II and you can farm for mats.
