Last time I tried (a few years ago) that I hadn't played for like, just 2-3 years, and suddenly instead if just being like a space ninja robot who goes to spaceships and bases and hits people with a sword until loot falls out of them, I was a person who owned space ninja suits, as were others (biiiiig change to the lore lol), who lived on a spaceship (!?!), there was a plot and a story and stuff, there were open-world planets I could and for some reason kind of had to go to, loot seemed to work significantly differently, and also I could do space combat stuff, and I had like 43 quests I was urgently supposed to do. I gave up after about 15 minutes of trying to understand what the hell was going on. It was quite of a pity because I really liked Warframe in Ye Olde Dayes.
