If you forgot to purchase them you'll have had some of your Squad Mates die, but that doesn't mean you shouldn't upgrade them after: each one will bolster the strength of the Normandy War Asset.

The Normandy can be upgraded with Heavy Armor, Multicore Shielding and a Thanix Cannon, which will help ensure no casualties when approaching the Collector Base in the run-up to the Suicide Mission. As mentioned above, War Assets affect a major decision at the end of Mass Effect 3, so you'll want as much of them as possible. There are several War Assets in Mass Effect 3 that are only available by performing certain actions in Mass Effect 2. War Assets contribute to a final score that determines your options and their effects in an important decision at the end of Mass Effect 3, so you'll want as much of them as possible.

For example, a Loyal Kasumi will become a War Asset after you meet up with her again. Several War Assets, an important resource in Mass Effect 3, can only be earned by importing a Mass Effect 2 Profile. This is a huge boon because having lots of Morality Points allows you to pick Charm / Intimidate options to resolve situations in your favour more easily. Importing a Mass Effect 2 Shepard will give bonus Morality Points at the start of Mass Effect 3. This means that a fully-leveled ME2 Shepard starts ME3 at Level 30 (halfway there), allowing you to enable many Powers and Talents right from the start of the game. Shepard's Level in Mass Effect 2 is carried over directly into Mass Effect 3, which returns to a Level Cap of 60. While Mass Effect 3 does let you use the Genesis 2 comic to make important choices in the first two games, it's nowhere near as granular as playing them outright, and starting fresh will result in a fair amount of missed content. The most obvious reason, by importing your Mass Effect 2 save you get to continue your specific Shepard with their reputation, choices, Romance and more. There are many very important reasons on why you'll want to import your Mass Effect 2 save to Mass Effect 3 over starting 3 fresh or using the Galaxy 2 comic add-on:
