No, not how I think it should be used.
Being able to plaster stickers all over your car isn't what for me what GT is all about, I like being able to race normal cars and I'm sure PD don't want there cars to be ruined by all the rubbish people would plaster over there cars.
Restricting livery's to only race cars and RM's means people could still do what they wanted but it would be restricted, best of both worlds?
Realistically I don't know. Painting the body and rims still keep them normal without going ott and is enough for me........
So yes, how
you think it should be used as that's not what GT is all about for
you (not taking into consideration what GT could be about for others, or what it could become eventually).
Restricting it to certain types of cars means restricting creativity and artistic freedom, you can obviously still choose not to use it for roadcars, isn't that enough?
I see a lot of roadcars with advertising decals promoting companies on the road, might not be to your liking but what if someone would like to create or replicate something like that for whatever reason?
Or if someone just wants to put hideous graphics on their roadcars just like people put hideous graphics on their real life cars, you and I may not like it but someone elses taste isn't for us to dictate.
Or when someone just wants to make their fully tuned and bewinged roadcar (with full weight saving, chassis reinforcement and downforce a roadcar basically already becomes a racecar apart from the way it looks)
look more like an acceptable raceversion instead of a questionably adorned tuner car.
Thing is, a livery editor is a gameplay element in itself, not just the result but the whole process of creating something is what people like me are looking forward to, you know,
playing around with it and not just having about 15 to 20 cars to use which'll become tiresome eventually.
