I have been playing TD1 lately, quite a bit. It runs a lot smoother on my PC and I want to get the shields that you can earn in TD2. However, I find, I really enjoy the snowy atmosphere and the city in New York a lot more than TD2's setting in Washington DC. The environmental storytelling with the drones, found footage, phones, etc also seems much better to me. The storyline in TD1 also is better and so are the main characters you interact with.
TD2 is much better gameplay wise, skills wise, guns wise, loot wise, and exploration wise, but I find myself enjoying the setting and minute to minute gameplay much more in TD1. Your thoughts? I do think TD2 will catch up over time, but it runs significantly worse and looks worse on my PC than TD1 for me as well. I find myself wanting to play TD1 more than TD2 these days.
