I stumbled accross OPR through Wyloch's Youtube channel. Read the rules and I am curious if anyone around here tried it in 15 mm and what would be the main adaptations to do.
Also, any suggestions for 15 mm miniatures? I've seen the pinned thread but they are not categorized by scale. I really wish I could play this kind of game and the open and free rules + 15 mm would greatly reduce the cost of entry.
I'm all geared up to hobby since I'm into Warhammer Underworlds.
Cant speak to 15mm but i have (with help) adapted the rules for 1/72 scale. Basically.. Apply the tough rule to the collective unit based on the model count. Tally damage taken by the unit instead of removing models individually. Otherwise, rules are as normal. I use 60mm square bases. 1 per 5 guys. The base size gives me creative freedom. So my units look like mini diaramas.
Ex: 5 guy unit on 1 base would be tough 5.. They wouldnt take their morale test until they take 3 damage .
Germans- about 900 pts based and painted US- about 900 pts based and primed Ancient Persians- about 900 pts not based yet Ancient Greeks- about 900 pts not based yet Zombies- About 450 pts based and painted- another 1300 pts to go
Another quick hack if you want to use 15mm on the fly but with the default 28mm rules -- just use centimeters instead of inches when you measure. e.g. 12" becomes 12cm.
Although with modern/future miniatures games, I find using 15mm with 28mm ranges also works just fine, since shooting ranges are generally compressed to fit the game table, but 15mm minis with 28mm distances 'feels' right if you have shooting games.
For melee/fantasy, I'd consider the inches to centimeters technique.
