Here is my Quality Slop list (I only like them because they are good):

• The Legend of Zelda: Ocarina of Time
• Metal Gear Solid
• NieR Gestalt
• Test Drive Unlimited 2
• Halo Combat Evolved
• Dark Souls
• The Elder Scrolls III: Morrowind
• Half-Life: Opposing Force
• Danganronpa 2: Goodbye Despair
• Silent Hill 2 (the original, not the remake)
• Super Metroid
• Need for Speed Underground 2
• Shenmue 1, 2, and 3 (Shenmue 3 is probably the worst game on this list, but its still pretty good regardless)
• Star Wars: Knights of the Old Republic 1 & 2
• Age of Empires II
• Command & Conquer: Generals - Zero Hour
• Policenauts
• Panzer Dragoon Orta

Each of these have contributed to my high bar of expected quality for games. Most of these games were made on a very tight budget and schedule, with pretty harsh hardware limitations, usually with a small team of less than 100 people, and are the greatest games of all time. Modern game studios have no excuses for the awful quality they launch games in today with more time, money, more people on the dev team, and lack of hardware limitations.
