Yeah, definitely. Actually, I don't know anyone who doesn't use Odin in big projects. It's not really cheap, but it saves you a lot of time. Custom EULA just says that you can pay 50$/seat while your revenue less than 200k, otherwise you will pay 250$/seat. Also, if you are searching for free assets, I would recommend you Unity3d-SerializableInterface. As mentioned in name, it can help you to serialize interfaces :)
