Those are two extremely different games and kind of hard to compare considering one is an fps and the other an rpg, since I don't like rpg's im gonna have to go with reach because the beta was really awesome. But most of my friends say that dragon age is really good if your into rpg's.
Even though the games are not out yet. From playing both of the betas, halo reach is probably going to be more fun and challenging compared to call of duty black ops. My reasons: becuz there forge (where you get to build your own maps and play on them with your friends or just drop tanks on each other.
Theres matchmaking were you get to go 4v4 or 1v6 or 3v3 and theres diffrent objectives like head hunter(kill a person and collect there skull and deliver it to the checkpoint) and capture the flag(a fun classic) where you capture the enemys flag and run to your base hoping you don't get killed and deliver it to your bases checkpoint. Theres gonna be a new gametype, Invasion which sets spartans against elites in an all out war against each other to capture a warehouse or successfuly defend a territory. Then there firefight an old gametype with a crazy change up.
It sets you and your teammates up against a set number of waves and you must complete each set and not lose all your lives in order to survive. Plus in halo reach you can customize your characters armor, color him the way you want, choose armor effects. Plus there story is considered to be amazing while call of duty is going to be....... anyways imo halo reach is going to be a great game way better than cod.
I looked up videos on youtube about the two games and I think reach will be the game of the year because it has new weapons and your dude will have power ups like invisibility, speed, jet packs, and protective over shields while cod blacks ops it looks good but I don't know about the online play because tryarck just stole the idea from mw 2 which means you can still get care packages and everything but the only thing that is going to be good about that game is the theater mood and new weapons but dude just go what you want to get but my choice is halo reach.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
