so i was showing some of the sprites to some of my artist coworkers and they told me that many of the backgrounds used scaled down images that were then cleaned up , this sort of opened my eyes because i used to think everything in games like metal slug was made from scratch , pixel by pixel . my boss has been in the gaming industry for the past 20+ years and has worked on some old school titles . he was the first one to let me know that these were clearly scaled down images since the perspective was all wrong in the first place and everything else such as the rendering on the objects were different from the rest of the art .he told me this used to be a common practice back in the day. do let me know what you guys think about this . was this common knowledge to everyone in the community?
