Ok so I have REALLY gotten into PC gaming as of late and I was wondering if anyone could be so kind as to give me their flat out opinion of it. All of them are steam games, 1. Terraria What I know: I know its basically 2D minecraft and its got a ton of vanilla content and cheap. 2. Half-Life(1) What I know: I know its hard and long (Be mature temp, be mature. :I) and that its a bit confusing but I also hear its much better then the "derped up" Half-Life 2, And I like what I have seen so far. 3. Half-Life 2 What I know: I heard it much easier then 1 and it has more shooty shooty and not so much "wtf puzzles?" the main reason I would buy this is to get all the source mods its based off of and the story. Anyway I just want to know if these are worth buying and such, Im pretty low on cash since I just pre-ordered SM3DL and been making payments, I just want to get a good game that will tide me over for the rest of the year and still have the playability to make me want to come back a month or 2 later and play it over.
