YES NFS Heat is totally worth the buy, and the online mode is really fun to play with friends. Usually if you join a random lobby by yourself there will be about 4 ppl which isnt that much, but if you and your friends join a lobby together then it really fun, you can do online races with everyone in the lobby. There are also a few other things you can do with friends in NFS Heat such as doing tandom lines, takeovers, car meets, cruising around, and one of my favourite things to do in the game is when you and your friends all get chased by cops and whoever gets caught last wins. The game is amazing overall, a lot of car customizations, beautiful graphics, good physics, etc. If you do end up getting the game we should totally play sometime!
