Re: Paragon VS Renegade VS Neutral
Sounds like you still have a lot of time to choose which path you want to take, though it's very possible to almost max out both paragon and renegade in one playthrough, especially if you're playing Legendary mode with the increased exp.
The problem with choosing only one path is it's not always clear exactly what the paragon and renegade options will end up doing in conversations. One minute your renegade points are earning you a few extra credits, the next they're pushing old ladies into oncoming traffic. My advice if you want a realistic experience is to just pick the option that feels right in the moment and you will probably find yourself with a lot of points in both paragon and renegade by the end of the game. Unless you want to choose a specific path, that is.
I usually go neutral, leaning slightly renegade because it makes you feel like a badass instead of an douchebag or a boy scout.
