I did some testing with games to make a score, and here are the results at the moment:
WineBottler: (freeware)
Notes:Variety of games (3 of 10 | 30%): 3.0
Quality of games that work (Notes from 3 games: 9,8,8) 8.3
Average: 5.65
Wineskin Winery: (freeware)
Notes:Game variety (22 of 25 | 88.0%): 8.80
Quality of games that work (Notes from 22 games: 18x10, 4x9): 9.81
Average: 9.30
Cider: (freeware)
Successful tests here: Doc's OfficeCross Over Games: (shareware)
Single test:
-Following the test suggested in Google searches
PlayOnMac: (freeware)
Single test:
-Insert game No-CD crack
-Copy the file from the MOVIES folder of the CD to the folder where the game was installed
-Obs.: The game can't be converted to APP
Ignore CrossOver Games, PlayOnMac and Cider, because they are not the focus.
And regardless, I think the Cross Over Games and the Wineskin Winery are the best! (but Wineskin is freeware, then wins XD)
