PoP: Please choose from PoP Short/Medium/Long/Very Long lists.
If any of the above lists is empty, pick from my SG wins (never played/unfinished), prefer games with achievements (especially the long ones). Don’t pick from red lists (Tried, Old).

Lists explain:
Tried: Don’t like those games, move them to low priority, maybe try them later.
Old: Incompatible to modern OS (win10/ubuntu), random crash, lose saves, DRM service discontinued (SecuROM, GFWL) etc. Unplayable.
