i have already rented this game and I am half way through. it is alright. I returned it yesterday and im wondering, should i but it 4 35$ then return it or should i just drop it all together

What you should do is keep renting it till you beatit and then if you decide its to challenging for ya drop the whole thing. If you do decide to get it,great, its got a solid story line too. If you like challenges and have an xbox live account i suggest playing. I dont have one,however, people say its awsome but you only realy have to look out for people trying to get stealthy knife kills all the time.
