the fact it shows how many people use which suplier is proof enough on who to go with,there should be visible stats for every suplier and a system were only the best teams can get the best supliers as the supliers them self desire big teams to use there engines,tires,fuel etc etc and if the little teams want to use the best parts they have to impress the suppliers with extensive vip/marketing events etc etc to build up a relationship with them for the future.
Also what would be good is the fact that suppliers would like to support a home nation team or a team that has a driver from the same nation as the supplier is based.
I just dont think igp is as extensive with this as other online f1 manager games,the stats and systems used in some site blow igp away and the limited nature of igp seems miles behind others,and dont get me started on the lack of qaulifying.
I think that you have to remember that this game has only been released for officially about six months, which is very young compared to a lot of other F1 management games, and the development team is two people at the moment, so in my opinion, they've done a fantastic job.
This game will continue to grow, and you can see that it has a lot of potential. Any 'weaknesses' will be ironed out I'm sure :)
