jcsilva87: What's the difference between the two individual Terminal Cut versions and the Terminal Cut Bundle?
They appear as 3 different games in the "Buy Series" option(see image attached).
They're listed as a series because they'll all technically listings for the same game series, but it's just two games.
The games are Bloodrayne and Bloodrayne 2. The bundle would just be both games sold as a bundle at a slightly lower price as compared to buying the games separately (although waiting for a sale would likely save you more money that the bundle, but who knows when they'll go on sale).
The original games aren't available any more. They've been replaced by the terminal cut versions which are remasters of the original games (Personally, I don't use the remasters because it breaks compatibility with mods I like to use, like cheating mods which I find essential because the boss battles are annoyingly difficult).
