God of War Collection - $3.74 (this contains GOW 1 and 2 in HD)
God of War Origins Collection - $2.49 (this has the 2 PSP games remastered to 1080p)
For some reason they didn't put GOW 3 in the PS3 list but you can get that on the PS4 and finish up with Ascension on PS3. Regular version should suffice.
Play them in order of release, no need to play them 'chronologically' (the Origins games are actually prequels to the main release). Playing them in release order will make the most sense in terms of story/plot/characters etc.
Release order:
GOW 1, 2, Chains of Olympus (from Origins Collection), 3, Ghost of Sparta (Origins), Ascension.
Chronological order:
Chains of Olympus, Ascension, GOW 1, Ghost of Sparta, GOW 2, GOW 3
