Audiosurf 2, OR Baldur's Gate Enhanced with Heretic + Hexen collection

Audiosurf 2
if you are fan of first one

personally id go with audiosurf two just because i loved the first one.

Audiosurf2, baldurs gate enhaced edition its not enough enhaced, personally think that old one looks better.

Heck with those other guys, I say go with Baldur's Gate and Heretic + Hexen! Much more fun to be had, if you ask me. =P

Go for Audiosurf 2, but don't be disappointed if at first you don't like it. As someone who bought it within the first 15 minutes of its release, I can tell you that it is VERY unpolished. Don't get me wrong, it's fun, but it's definitely got some room for improvement before the non-early access release.

You can pick up the original baldur's gate for very few on gog, the enhanced version kinda sucks. Go for Audiosurf 2.

Based on your gaming history, you seem more geared towards FPS and action games. That means you probably won't like Baldur's Gate. It requires patience and a willingness to learn the in-depth DnD system it's based on. Also, it's an old school RPG and therefore has a lot of reading. Some people don't like to read.

I'd say: wait for Audiosurf 2 to get discounted. Get something discounted in the meanwhile.

Get Baldurs gate and Audio Surf (1st one when its -75% off).

Audiosurf 2

Audio Surf 2 has a lot of potential but is extremely unpolished and buggy for me in its current state. If you like older games I would say go for Hexen/Heretic and Balders Gate then pick up Audio Surf 2 when it goes on sale or is more polished and closer to finish.

I loved Audiosurf so I'd go with Audiosurf 2

Baldur's Gate and Heretic + Hexen have my vote. However I am partial to them as I played both a lot when I was younger.

Some games I think you might be interested in ( who knows you might not.. but they are 15 USD and under. )
Volgarr the Viking
Mercenary Kings
Spelunky
Rogue Legacy
Final Fantasy 7
Dungeons & Dragons: Chronicles of Mystara

I could probably mention a few more if you want that are also 15 USD and under. However I will say that you might want to wait and see if the D&D one goes on sale if you want to get it.
